VOIP for Law Firms Australia: Compliance, Features and Recommendations (2026)

This guide covers everything an Australian law firm needs to know about VOIP phone systems: which features matter for client experience and professional reputation, how call recording works under state-by-state Australian law, what client confidentiality requires from your provider, and what a properly sized setup looks like from sole practitioners through to multi-office firms. Unlike generic VOIP guides, this one addresses the specific call flow challenges of legal practices, the compliance obligations under the Legal Profession Uniform Law and state-based recording legislation, and the real cost of missed client calls. By the end, you will know exactly what to ask a provider, what questions to raise with your practice manager, and what a complete law firm phone system looks like.

Why Law Firms Need a Proper Phone System

Most Australian law firms are still running on whatever telephone service came with the office lease or the ISP package. That typically means a basic landline, an NBN plan with a green ATA port on the modem, or an aging on-premise PBX that nobody knows how to configure properly. It takes calls. It does not project the professionalism a legal practice is supposed to represent.Here is what that basic setup costs a law firm in real terms. A prospective client calls about a matter that could generate $5,000 to $50,000 in fees. The phone rings out because the receptionist is with another caller. There is no voicemail. The client calls another firm. That lead is gone permanently. At even one missed prospective client call per week, the annual revenue cost of an inadequate phone system is material.The person who usually gets handed the job of fixing the phone system is not a partner. It is the practice manager, the office manager, or the firm administrator. They are experts in running legal operations, not in telecommunications infrastructure. If that is you, this guide is written for you specifically. You are not behind. The industry made this confusing on purpose, and most law firms your size are in exactly the same position.Beyond client acquisition, law firms have obligations that other small businesses do not. Call recording may be required for file notes and matter records. Client communications must be confidential. Data sovereignty matters when client privilege is at stake. A generic ISP phone plan does not address any of this. A properly configured hosted VOIP system does.

The Business Case: What a Missed Client Call Actually Costs

Legal services are high-consideration purchases. A potential client calling a law firm has usually already decided to engage a lawyer. They are calling to determine which firm. If that call goes unanswered or hits a poor voicemail experience, there is no second chance. The next firm on their list answers and the matter goes there.The cost calculation is straightforward. For a firm billing at $250-500 per hour with matters running 10 to 40 hours, a single lost prospective client represents $2,500 to $20,000 in foregone revenue. A properly configured VOIP system with call queuing, voicemail-to-email, and after-hours routing for a small law firm costs $200-500 per month including handsets amortised over three years. The business case does not require a financial model. It requires losing one matter.Beyond new business, there is the matter of existing client relationships. Legal matters are stressful. Clients who cannot reach their solicitor feel anxious, not just inconvenienced. Missed calls erode trust during exactly the period when trust matters most. A phone system that routes calls predictably, provides professional voicemail, and delivers messages directly to solicitor email inboxes is not a luxury feature. It is basic client service infrastructure.

Call Recording for Law Firms: State-by-State Australian Law

Call recording is one of the most useful features a law firm can have in a phone system. It creates a record of client instructions, confirms file notes, resolves disputes about what was agreed, and provides evidence in complaints processes. It is also an area where the law varies by state and where getting it wrong has professional consequences.Australian call recording law is primarily governed by state-based listening devices and surveillance legislation, not a single national framework. The key distinction is between one-party consent and all-party consent jurisdictions.

One-Party Consent States: Queensland and Northern Territory

In Queensland (Invasion of Privacy Act 1971) and the Northern Territory (Surveillance Devices Act 2007), a participant in a private conversation may record that conversation without notifying the other party. In practical terms, a solicitor in Queensland can record a client call without first telling the client the call is being recorded, and that recording is lawful. The solicitor is a participant in the conversation and the one-party consent rule applies to them.Even in one-party consent jurisdictions, best practice for law firms is to notify callers that calls are recorded. The notification removes any ambiguity, builds trust with clients who appreciate transparency, and aligns with the professional obligation to be straightforward in client dealings.

All-Party Consent States: Victoria, New South Wales, ACT, South Australia, Western Australia, Tasmania

In Victoria (Surveillance Devices Act 1999), New South Wales (Surveillance Devices Act 2007), ACT (Listening Devices Act 1992), South Australia (Surveillance Devices Act 2016), Western Australia (Surveillance Devices Act 1998), and Tasmania (Listening Devices Act 1991), recording a private conversation requires the consent of all parties. Recording without notification is unlawful.For a law firm in these states, call recording must be preceded by a notification message that callers hear before their call is answered. The standard approach is an IVR message played automatically at the start of every inbound call: 'This call may be recorded for quality assurance and file note purposes.' That single sentence, if played before the call is connected to a staff member, satisfies the notification requirement in all-party consent jurisdictions.This notification message must be configured in your VOIP system before call recording is enabled. If your system records calls but does not play a notification first, and you are in an all-party consent state, every recorded call is a potential breach of state surveillance legislation. This is not a grey area.

Call Recording Storage and Retention for Legal Practices

Call recordings that relate to a client matter are potentially part of the file. Legal profession rules in all Australian jurisdictions require files to be retained for defined periods after a matter closes. In most states, the minimum retention period for client files is seven years. Check your jurisdiction's specific requirements under the Legal Profession Uniform Law (applicable in NSW, Victoria, and WA) or equivalent state-based legislation.When evaluating VOIP providers, ask these specific questions about call recording storage. How long are recordings retained on the provider's servers? Can the retention period be configured? Can recordings be downloaded and stored locally or in a practice management system? Are recordings deleted automatically after a set period? A provider that retains recordings for only 30 or 90 days by default is inadequate for a law firm that needs to retain matter-related recordings for seven years.The practical recommendation is to download and archive call recordings to your practice management system or document management platform as part of your file management workflow, rather than relying on the VOIP provider's server as the long-term storage location. Treat call recordings as file documents: name them, date them, and store them against the relevant matter.

Client Confidentiality and Data Sovereignty

Solicitor-client privilege is a fundamental principle of Australian law. The obligation of confidentiality extends to all communications between a solicitor and their client, including telephone calls. When a law firm moves its phone system to a cloud VOIP service, client communications pass through and are stored on a third-party provider's infrastructure. Understanding where that infrastructure is located and who has access to it is not optional.

Data Sovereignty: Australian-Hosted Cloud

The Privacy Act 1988 and the Australian Privacy Principles (APPs) govern the handling of personal information by Australian businesses. APP 8 addresses cross-border disclosure of personal information. If a VOIP provider stores call data, voicemail recordings, or call logs on servers located outside Australia, the law firm must take reasonable steps to ensure that overseas handling is consistent with Australian privacy obligations.For a law firm, the practical implication is straightforward: use a VOIP provider whose infrastructure is hosted in Australia. Client names, matters discussed, instructions provided by telephone, and any personally identifiable information contained in voicemail messages should not be routed through or stored on US servers, even if the provider is nominally an Australian company. Ask explicitly: where is call data and voicemail data stored? Which data centres? Are they located in Australia?Providers that cannot answer this question clearly, or that acknowledge overseas storage without being able to articulate what cross-border data agreements are in place, should be disqualified from consideration by any law firm. This is not a question of being overly cautious. It is a question of meeting your professional obligations to clients.

Encryption and Access Controls

A reputable hosted VOIP provider encrypts calls in transit using SRTP (Secure Real-time Transport Protocol) and secures the signalling layer with TLS (Transport Layer Security). This means calls between your VOIP phones and the provider's servers are not transmitted in plaintext and cannot be trivially intercepted. When evaluating providers, ask whether calls are encrypted in transit. A provider that cannot confirm SRTP and TLS encryption should not handle client communications for a law firm.Access controls on your VOIP account are equally important. Your VOIP management portal, where call recordings, call logs, and voicemail messages are stored, should be accessible only to authorised staff with individual login credentials. Shared passwords for a multi-user system are an access control failure. A firm administrator or practice manager should be able to provision and deprovision individual user access as staff change without needing to reset shared credentials.

Essential VOIP Features for Australian Law Firms

Not all VOIP features matter equally to a law firm. The features below are the ones that directly affect client experience, professional image, operational efficiency, and compliance. These are the baseline requirements for any legal practice, regardless of size.

Direct Inward Dialling (DID) per Solicitor

A DID number is a direct telephone number that rings to a specific extension or solicitor's phone without going through reception. In a law firm context, this means each solicitor can have their own direct telephone number that existing clients, counsel, and courts can call directly. The solicitor's direct number appears on their correspondence, business card, and email signature. Clients who have an established relationship call direct; new enquiries come through the main number.DIDs are inexpensive on a hosted VOIP system. Most Australian providers charge $5-15 per month per DID number. For a five-solicitor firm, providing each solicitor with a direct number costs $25-75 per month on top of the base plan. The professional and operational value is significant: reception workload decreases, existing client calls reach solicitors without delay, and the firm projects a level of professionalism that a single shared number cannot.

Ring Groups by Practice Area

A ring group causes multiple phones to ring simultaneously or in sequence when a call comes in. For a multi-practice-area firm, ring groups allow callers to be routed to the relevant team without putting them through a lengthy IVR menu. A caller pressing 1 for property matters rings all property solicitors simultaneously; the first available one answers. A caller pressing 2 for family law rings the family law team.Ring groups also serve as a continuity mechanism. If one solicitor is in a consultation and another is available, the ring group ensures the call does not go to voicemail unnecessarily. For a small firm where every call matters, ring group configuration is one of the highest-value features in the system.

After-Hours Routing with IVR

Law firm calls do not respect business hours. Clients in distress, counterparties with deadlines, and solicitors calling from different time zones all generate after-hours call attempts. Without a properly configured after-hours routing plan, those calls go unanswered and create a poor impression.A well-configured after-hours IVR for a law firm might: confirm the firm's name and business hours, offer callers the option to leave a voicemail that will be actioned the following business day, provide an emergency contact number for urgent matters (if the firm has one), and direct callers to the firm's website for general enquiries. This is the minimum configuration. For firms that handle matters with genuine urgency (criminal law, family violence, urgent commercial applications), a direct mobile forwarding option for after-hours urgent calls can be added as a conditional routing rule.

Voicemail-to-Email with Transcription

Voicemail-to-email delivers voicemail messages as audio file attachments to a nominated email inbox. For a solicitor working across matters and meetings, being able to review a client voicemail from a laptop during a break is more practical than dialling into a voicemail box between appointments. When the voicemail-to-email function includes transcription (converting the audio to text), solicitors can read the message content in an email preview without listening to the audio at all.Transcription accuracy varies by provider and depends on audio quality and accents, but even imperfect transcription is useful for determining urgency before listening to the full message. For a law firm managing high volumes of client communications, voicemail transcription reduces the friction between a client leaving a message and a solicitor actioning it.

Call Transfer and Park

Call transfer allows reception to connect a caller to a specific solicitor or extension without requiring the caller to hang up and redial. For a law firm, a warm transfer (where reception briefly speaks to the solicitor before putting the caller through) is often more appropriate than a blind transfer, particularly for client calls that reception has already qualified or for sensitive matters where the solicitor needs a moment's context.Call park allows reception to hold a call on a shared line and signal to a solicitor that a call is waiting for them, without transferring it blind. This is particularly useful in open-plan offices or where solicitors are visible from the reception desk. The solicitor picks up the parked call from their own phone when ready.

Conference Calling

Three-party conference calling is standard on hosted VOIP plans. For law firms, this covers the routine requirement of connecting a client, a solicitor, and a third party (counsel, an expert witness, a counterparty's lawyer) on a single call. For larger conference calls involving multiple participants, a dedicated audio conferencing bridge is more appropriate than trying to manage multiple transfers in the PBX. Most hosted VOIP providers include basic conferencing, and some include bridge access for larger calls.

Presence Indicators and Busy Lamp Field

Presence indicators show reception staff which solicitors are currently on calls, which are available, and which are in do-not-disturb mode. On a SIP desk phone with a BLF (Busy Lamp Field), each monitored extension is represented by a light on the phone: green for available, red for on a call, and flashing for ringing. For a reception desk managing calls for four to ten solicitors, BLF capability is a significant productivity feature. Reception can see at a glance who is available before transferring a call, rather than putting callers on hold to manually check.

Integration with Practice Management Software

Australian law firms use a range of practice management systems. The four most commonly encountered in the small-to-mid firm segment are LEAP, Actionstep, Smokeball, and Clio. Understanding how VOIP interacts with these platforms avoids disappointment during implementation.

Direct Integration: What Is Realistic

True CTI (Computer Telephony Integration) -- where an incoming call automatically opens the relevant matter file in LEAP or Clio based on the caller's number -- is available from some enterprise VOIP platforms but is uncommon in the SMB-focused hosted VOIP market. If screen-pop integration with your specific practice management software version is a priority, confirm explicitly with any provider before signing up. Most providers in the Australian SMB market do not offer this as a standard feature.For most law firms, the realistic integration outcome is parallel operation: the VOIP system handles call routing and recording, while the practice management software handles matter records, time recording, and billing. The solicitor or support staff takes the call in the VOIP system and opens the relevant matter in LEAP or Actionstep separately. This is how the majority of Australian law firms operate today, and it works without any technical integration.

Time Recording from Call Data

VOIP call logs record the duration, time, and number for every call. In a law firm, this data can support time recording. A solicitor reviewing the day's call log can verify the duration of client calls and record time entries accordingly, particularly for calls that were not pre-scheduled and therefore not already blocked in the diary. The VOIP call log is not a substitute for the practice management system's time recording module, but it is a useful cross-reference and a prompt for solicitors who miss recording a time entry at the time of the call.

Reception Desk Setup for Law Firms

A law firm reception desk has specific requirements. The person at the desk needs to manage multiple simultaneous calls, transfer calls with context, identify which solicitors are available, and project professionalism to clients calling about significant matters. The right equipment makes all of this manageable.For the primary reception position: a mid-to-high-range SIP desk phone with a colour display, BLF capability, and a headset port is the standard recommendation. The Yealink T54W and T46U are widely used in Australian professional services firms. The colour display allows clear indication of call status across multiple lines. The BLF panel shows solicitor availability. The headset port allows hands-free operation during long call periods, which reception staff in busy firms require.For firms with high call volumes or where reception manages more than six simultaneous extensions, a sidecar expansion module can be added to a compatible desk phone to extend the number of BLF-monitored lines. This allows a single receptionist to monitor twelve or more solicitor extensions without switching screens or guessing who is available.For individual solicitor desks: a basic to mid-range SIP desk phone is sufficient for most solicitors who do not need to manage complex call routing from their own desk. The Yealink T31P is a reliable, cost-effective option for solicitor extensions where the primary requirement is making and receiving calls. For senior solicitors who prefer not to have a physical handset, a softphone application on their desktop computer or laptop provides full VOIP functionality without dedicated hardware. See our SIP desk phone guide for detailed model comparisons and Australian pricing.

1300 Numbers for Law Firms

A 1300 number routes calls to your existing phone system and presents a single national contact number regardless of where your offices are located. For law firms, 1300 numbers have several practical applications.For a firm with multiple offices (a Sydney office and a Parramatta office, for example), a single 1300 number means clients call one number and are routed to the appropriate office based on time-of-day rules, the IVR option they select, or a default routing preference. This avoids clients having to maintain separate numbers for each office and ensures enquiries reach the right location without requiring the caller to know which office handles their matter type.For marketing and advertising, a 1300 number has tracking and measurement capabilities that a geographic number does not. If your firm runs different marketing channels (print, digital, referral programs), separate 1300 numbers can be assigned to each channel. Call analytics on the VOIP platform then show which channels are generating calls, allowing informed marketing spend decisions. This capability is not available on a single shared geographic number. For a full breakdown of how 1300 numbers work and their cost structure, see our 1300 number guide.One important consideration for law firms: callers to a 1300 number pay the cost of a local call from landlines and a mobile flagfall charge from mobiles. Clients with legal matters often call repeatedly and may be cost-sensitive about mobile call charges. Some firms choose to provide both a geographic local number and a 1300 number, listing the geographic number prominently for existing clients and the 1300 number for advertising.

Recommended Setup by Firm Size

Handset hardware is a one-off capital cost. Entry-level SIP desk phones suitable for solicitor extensions run from $120-200 per handset (AUD, check current pricing). Mid-range reception phones with BLF capability run $250-450 per unit. For a five-solicitor firm with a reception desk, expect a total hardware outlay of $800-1,800. Most hosted VOIP providers can pre-configure handsets before delivery so they register to your account and work when plugged in, without requiring your team to configure SIP credentials.

The Australian Infrastructure Context for Law Firms on NBN

Australian law firms operating from offices on NBN broadband are already using VOIP, whether they know it or not. The copper PSTN network was switched off progressively from 2020 onwards. If your office has an NBN connection, the phone line is already running as VOIP through the ISP-controlled ATA adapter on your modem. The difference between that setup and a proper hosted VOIP system is not the technology. It is who controls the service, what features it includes, and whether it meets your professional obligations.NBN call quality for VOIP depends on your connection type. FTTP (Fibre to the Premises) and HFC are generally stable for voice calls. FTTN (Fibre to the Node) can introduce jitter and packet loss depending on the length of the copper segment from the node to your building. If your firm has experienced call quality issues on NBN, FTTN is the likely cause. For a law firm where call quality directly affects client relationships, it is worth investigating whether an FTTP upgrade is available for your premises. Nbnco's rollout of FTTP has expanded coverage in many metropolitan areas. See our VOIP call quality guide for NBN-specific diagnostics and remediation steps.One critical operational note: NBN VOIP requires electricity to operate. If your office loses power, the phone system goes down unless the modem and router are connected to a UPS (Uninterruptible Power Supply). For a law firm where client calls must be answered and client matters have deadlines, a basic UPS on network equipment is cheap insurance. A suitable UPS for a modem and router costs $150-300 and provides 30-90 minutes of runtime during a power outage, which covers the majority of short outages. Most hosted VOIP providers also offer mobile failover, where calls are automatically forwarded to a nominated mobile if the system detects that the office phones have gone offline.

Number Porting for Law Firms

If your firm has an existing telephone number that appears on letterhead, court documents, marketing materials, and client records, porting that number to a new provider is essential. Number porting in Australia is governed by ACMA regulations and typically takes 5-10 business days for geographic numbers. Your existing number continues to receive calls during the port. There is no period of downtime where the number is unreachable.The porting process is initiated by your new VOIP provider, not by you. You provide your existing account details and the number(s) to be ported, and the new provider manages the transfer with your current carrier. The main risk is miscommunication about the port date: if reception staff are not informed that the port is happening and when, they may believe the new system is not working when calls appear on the new handsets rather than the old ones. Plan the port date carefully and brief all relevant staff in advance.For firms with both geographic local numbers and 1300 numbers, both can typically be ported. 1300 numbers are ported through the Telephone Numbers Allocations Committee (TNAC) system and may have slightly different timelines. Confirm porting capability for all numbers with any provider before signing up. For a full walkthrough of the porting process, see our VOIP call quality guide.

Choosing a Hosted VOIP Provider: What Law Firms Should Ask

The provider selection process for a law firm needs to include questions that would not appear on a generic SMB checklist. Before committing to any provider, get written answers to the following.Data storage: are call recordings, voicemail messages, and call logs stored on Australian servers? Which data centres? What is the retention period and can it be configured per account?Call recording: does the system play a notification message before calls are recorded? Is this configurable? Can recordings be downloaded individually and in bulk?Encryption: are calls encrypted in transit using SRTP and TLS? Is this enabled by default or does it need to be configured?Access controls: can individual users be provisioned and deprovisioned? Is multi-factor authentication available for the management portal?Support: is support provided by Australian-based staff? What is the response time commitment for outages during business hours?Contract terms: what is the minimum contract period? What are the exit provisions? Under Australian Consumer Law, standard form contracts cannot include unfair contract terms. Ask for the contract in advance and review it before signing. For broader context on how hosted VOIP providers compare, see our VOIP phone system guide and our hosted PBX vs on-premise guide.

What Law Firms Get Wrong: Common Mistakes

These are the mistakes law firms and their practice managers make most often when upgrading or selecting a phone system. All of them are preventable.

Mistake 1: Enabling Call Recording Without a Notification Message

This is the most serious compliance error a law firm can make with a VOIP system. Enabling call recording in the provider portal without first configuring a notification IVR message means every call recorded in an all-party consent state is a potential breach of state surveillance legislation. The fix takes five minutes: configure an IVR message that plays at the start of every inbound call before any recording begins. Do not enable call recording until this is in place. Do not assume the provider has configured it. Check it yourself by calling the main number and confirming you hear the notification before the call is answered.

Mistake 2: Buying Handsets Before Setting Up the Service

A SIP desk phone requires a VOIP account and a configured service to function. It does not have a dial tone out of the box. Firms that purchase Yealink or Polycom handsets thinking they will set up the service later end up with expensive paperwork holders. The correct order is: select a VOIP provider, set up the account and plan, configure extensions and ring groups, then provision handsets. Handsets come last. Read our business phone system guide for a complete walkthrough of the setup sequence.

Mistake 3: Choosing a Provider Without Confirming Australian Data Storage

A provider with Australian branding and Australian customer support may still store call data on servers located in the US or Singapore. For a general business, this is a minor inconvenience. For a law firm handling privileged client communications, it creates Privacy Act cross-border disclosure obligations and raises legitimate questions about the security of client confidences. Confirm data storage location in writing before signing any contract. If the provider cannot confirm Australian hosting, that is your answer.

Mistake 4: No After-Hours IVR Configuration

Many firms that do migrate to a hosted VOIP system never properly configure after-hours routing. Calls outside business hours ring out or go to a generic voicemail greeting. Prospective clients calling after hours with an urgent matter hear nothing useful and move on. Existing clients in stressful situations get no information about when the firm reopens or what to do for urgent matters. After-hours IVR configuration takes less than an hour to set up correctly and should be the first thing confirmed before the system goes live.

Your Next Steps: Getting Your Firm's Phone System Right

A structured approach makes this manageable even if you have no prior experience with VOIP or phone systems. Work through these steps before talking to any provider.Step 1 -- Map your current call flow. Write down what actually happens when a call comes into the firm now: how many lines ring, who answers, what happens when solicitors are in consultations, what happens after hours, and what number appears on the firm's letterhead. This is the baseline you are replacing.Step 2 -- Count your seats. A seat in a hosted VOIP context is the number of simultaneous call paths you need. Count reception positions, solicitor extensions (desk phones or softphones), support staff phones, and any mobile staff who need to receive firm calls. For most small-to-mid firms, the seat count is lower than the staff headcount because not everyone needs to be on a call simultaneously.Step 3 -- Identify your compliance requirements. Determine which state your firm primarily operates in and whether you are in an all-party consent or one-party consent jurisdiction for call recording. If you operate across multiple states, default to all-party consent rules for your notification message. Note any file retention obligations relevant to call recordings in your jurisdiction.Step 4 -- Define your after-hours requirements. What should happen when the firm is closed? Does anyone need to be reachable for urgent matters? What message do you want prospective and existing clients to hear outside business hours? Write this out in plain language before talking to a provider.Step 5 -- Prepare your provider evaluation checklist. Using the questions in the provider selection section above, prepare a list of written questions to send to any provider you are evaluating. Providers that cannot answer these questions clearly should be deprioritised.Step 6 -- Get a recommendation. With your seat count, call flow requirements, compliance checklist, and questions prepared, talk to a VOIP specialist who can recommend a plan and configuration appropriate for a legal practice. See the link below to submit your details and get a personalised recommendation.Step 7 -- Plan your number port. If you are moving existing numbers to a new provider, initiate the porting request as early as possible. Allow 5-10 business days and brief all staff on the transition date. Do not cancel your current service until the port is confirmed complete.

Law firms often need more concurrent lines than their headcount suggests, partners, associates, and reception staff may all be on calls simultaneously during busy court periods. Our Phone Lines Calculator estimates your realistic peak concurrent call requirement.

Is it legal to record calls in a law firm without telling clients?

It depends on which Australian state or territory you are in. In Queensland and the Northern Territory, one-party consent rules mean a participant in a call may record it without notifying the other party. In all other states and territories (NSW, Victoria, ACT, South Australia, Western Australia, and Tasmania), all-party consent rules apply and you must notify callers before recording. Best practice for all law firms regardless of jurisdiction is to play a notification message before every recorded call. This removes ambiguity, supports professional obligations, and builds client trust.

How long do we need to keep call recordings as a law firm?

Call recordings that relate to a client matter are potentially part of the file. Under the Legal Profession Uniform Law (applicable in NSW, Victoria, and WA) and equivalent state legislation, client files must generally be retained for a minimum of seven years after a matter closes. The default retention period on most VOIP provider servers is 30-90 days, which is insufficient for legal practice. Download and archive matter-related recordings to your practice management system or document management platform as part of your file management workflow. Treat call recordings as file documents.

Can we keep our existing law firm telephone number when switching to VOIP?

Yes. Australian geographic numbers and 1300 numbers can be ported to a new VOIP provider. Number porting in Australia is governed by ACMA rules and typically takes 5-10 business days. Your existing number continues to operate during the port. The process is initiated by your new provider. There is no period of downtime where the number is unreachable. Confirm porting capability with any provider before signing up, and brief reception staff on the port date to avoid confusion when calls begin appearing on the new system.

Does a cloud VOIP provider have access to our client calls?

A hosted VOIP provider processes call data through their infrastructure, which means they technically handle the call signal. Reputable providers encrypt calls in transit using SRTP and TLS, limiting exposure during transmission. The more relevant question is where call recordings and voicemail messages are stored and who has administrative access to them. Ask any provider explicitly: which staff can access stored call recordings and voicemail messages? Are calls encrypted in transit? Where is data stored? For a law firm, these are not optional questions.

What is the difference between a DID number and the main firm number?

The main firm number is the number that appears on the firm's general letterhead and is used for new enquiries. A DID (Direct Inward Dial) number is a separate telephone number assigned to a specific solicitor or extension that allows callers to reach that person directly without going through reception. Both numbers ring on the same VOIP system. DIDs allow existing clients to bypass reception and reach their solicitor directly, reduce reception workload, and allow each solicitor to have a direct number on their own correspondence and business card.

What happens to our phones if the internet goes down at the office?

A hosted VOIP system requires an active internet connection. If the NBN connection goes down, office phones will not receive calls. Configure a mobile failover number with your VOIP provider so that calls are automatically forwarded to a nominated mobile if the system detects that office phones are offline. For power outages, connect your modem and router to a UPS (Uninterruptible Power Supply) to maintain the internet connection and therefore the phone system during short disruptions. A suitable UPS costs $150-300 and provides 30-90 minutes of runtime.

Should a law firm use a 1300 number or a local geographic number?

Most law firms benefit from having both. The local geographic number (02, 03, 07, or 08 prefix matching the firm's suburb) builds community trust and is preferred by clients who specifically want a local firm. The 1300 number serves advertising, multi-office routing, and call tracking for marketing channels. For a single-office firm serving a local client base, a geographic number should be the primary listed contact. For a multi-office firm or one that advertises nationally, a 1300 number becomes more useful. Read our 1300 number guide for a full cost and use-case breakdown.

Can VOIP integrate with LEAP, Actionstep, Smokeball, or Clio?

Direct CTI integration, where an incoming call automatically opens the relevant matter file in your practice management system, is available from some enterprise VOIP providers but is not standard in most SMB-focused hosted VOIP plans. For most Australian law firms using LEAP, Actionstep, Smokeball, or Clio, the realistic approach is parallel operation: the VOIP system handles call routing and recording, and the solicitor or support staff opens the relevant matter record in the practice management system separately. This works well in practice and does not require any technical integration. If screen-pop functionality is essential, confirm compatibility with your specific software version before committing to a provider.
