Best DECT Cordless Phones for Office Australia (2026)

This guide covers every decision point for choosing a DECT cordless phone for an office or business environment: range, battery life, multi-handset pairing, IP DECT versus analog DECT, and compatibility with hosted PBX and VOIP phone systems. Most buyers arrive at this page from the wrong direction -- they have found a cordless phone they like and want to know how to connect it. The actual first step is confirming you have a VOIP-compatible phone system in place. Once you have that, choosing the right DECT handset is straightforward. This guide explains both steps with Australian pricing and real deployment notes.

Top DECT Cordless Phone Picks for Business

What DECT Cordless Phones Actually Cost in Australia

IP DECT systems for business are sold as a handset-plus-base-station combination. The base station connects to your network and registers with your hosted PBX or on-premise phone system. Additional handsets pair to the same base. Budget roughly $350-550 AUD for a complete single-handset IP DECT system (base plus one handset). Each additional handset adds $90-160 depending on model. Multi-base enterprise systems -- where multiple base stations cover a larger area and handsets roam between them -- are available from Yealink (W80B DECT Manager) and Grandstream (DP755), with pricing from approximately $400-700 AUD per base station.Consumer DECT phones (Panasonic, Uniden, Oricom sold at JB Hi-Fi and Officeworks) typically run $80-250 AUD for a base plus two to four handsets. These connect to an analog phone port -- either the green port on your ISP modem or an ATA adapter -- not to a SIP-based phone system. They are cheap but they are not business VOIP phones and do not register with a hosted PBX. The distinction matters enormously, which is why this guide covers both the hardware decision and the underlying service decision.

What Is a DECT Phone and Why Do Businesses Use Them?

DECT (Digital Enhanced Cordless Telecommunications) is the radio standard used by virtually all cordless phones sold in Australia, Europe, and most of the world. It operates in the 1.9 GHz frequency band in Australia, which keeps it clear of Wi-Fi (2.4 GHz and 5 GHz) and reduces interference in busy office environments. DECT uses digital encryption between the handset and base station, providing better security and audio quality than older analog cordless standards.Businesses use DECT phones where staff need to move around while on a call: warehouse floors, retail spaces, medical practices where clinicians move between rooms, workshops, and small offices where a fixed desk phone does not suit every role. DECT gives you the call features of a proper phone system on a portable handset -- hold, transfer, call waiting, voicemail -- without the physical constraint of a desk phone.

IP DECT vs Analog DECT: The Decision That Actually Matters

This is the most important technical distinction for any business buyer, and it is the one most often missed. The two types of DECT system connect to your phone service in completely different ways and have fundamentally different capabilities.

Analog DECT (Consumer-Grade): What It Is and What It Cannot Do

Consumer DECT phones connect to a standard analog telephone line via an RJ11 connector. In the context of modern Australian offices, that RJ11 line comes from one of two sources: the green phone port on your ISP-supplied modem (an ATA adapter built into the modem firmware) or a standalone ATA device connected to your router. Either way, the phone connects to a traditional phone line signal. It does not speak SIP. It cannot register with a hosted PBX. It cannot access ring groups, call recording, extensions, or multi-site features.

IP DECT (Business-Grade): How It Actually Works

IP DECT phones connect their base station to your office network via an Ethernet (RJ45) cable. The base station registers directly with your hosted PBX or on-premise phone system as a SIP endpoint -- exactly the same as a wired SIP desk phone. Handsets then pair wirelessly to the base station using the DECT radio standard. The result is a cordless phone that has all the features of your business phone system: extensions, ring groups, hold, transfer, call recording, voicemail-to-email, and so on.IP DECT base stations are configured the same way as any SIP desk phone: you enter SIP account credentials (from your hosted PBX provider) into the base station's web interface, or use auto-provisioning if your provider supports it. Yealink and Grandstream DECT systems both support auto-provisioning with major Australian hosted PBX providers.

Base Station Requirements: What You Need Before Buying Handsets

Every IP DECT handset requires a compatible DECT base station on your network. Handsets do not connect directly to your router or phone system -- they pair to the base station, and the base station talks to your VOIP system. This means for every set of handsets you deploy, you need at least one compatible base station on your LAN.Base station capacity varies by model. The Yealink W70B supports up to five registered handsets and four simultaneous calls. The Grandstream DP752 also supports five handsets and four simultaneous calls. The Grandstream DP755 scales to ten handsets and ten simultaneous calls. For larger deployments, Yealink's W80B multi-cell DECT Manager system allows multiple base stations to be managed together with handset roaming across the coverage area.

DECT Range: What the Specs Mean in Practice

DECT manufacturers typically quote outdoor open-area range of up to 300 metres. Indoor range through walls and floors is always significantly lower -- in practice, expect 30-50 metres in a standard office with concrete walls and floors, or up to 100 metres in an open warehouse. The DECT 6.0 standard (used in North America) and the European/Australian DECT standard use different frequencies but both deliver similar real-world indoor ranges.For multi-storey buildings or large floor plates, a multi-cell DECT deployment (multiple base stations configured to work together) is the correct solution. Yealink's W80B system and similar enterprise DECT solutions allow seamless handset roaming between base stations, so a user walking from one end of a warehouse to the other stays on the call without dropping.

Battery Life: What to Expect

Business-grade IP DECT handsets typically offer 15-30 hours of talk time and 200-400 hours of standby. The Yealink W76H and W73H both claim up to 30 hours talk time, which means a handset could, in theory, be in active use all day without recharging. In real-world use -- a mix of calls and idle time -- a single charge easily covers a full working week for moderate call volumes.Grandstream DP730 and DP722 handsets offer 20 hours talk time and 250 hours standby -- still more than adequate for most business use. The difference in battery life between Yealink and Grandstream DECT handsets is unlikely to be a deciding factor for most buyers. What matters more is whether the handset supports the DECT base station you are deploying and whether it integrates with your hosted PBX's provisioning system.

Multi-Handset Pairing: How Many Can You Connect?

Each DECT base station supports a fixed maximum number of registered handsets and simultaneous calls. These two numbers are different and both matter. You might have five registered handsets but the base station only supports four simultaneous calls -- meaning if all five users try to call at once, one call will fail. Match your base station capacity to your actual simultaneous call volume, not just your headset count.For a small business with five staff where two or three might be on calls simultaneously, a single Yealink W70B base station with W73H or W76H handsets is sufficient. For a business where all five staff regularly take calls at the same time, consider the Grandstream DP755 (ten handsets, ten simultaneous calls) or a multi-base deployment.

Yealink DECT Range: W73H and W76H

Yealink's DECT range is the most commonly deployed IP DECT solution in Australian SMBs. The current mainstream handsets are the W73H and W76H, both designed to pair with the W70B base station.The Yealink W73H is the standard entry model: 2.4 inch colour screen, 30 hours talk time, contact list up to 1000 entries, and full SIP feature support including hold, transfer, conference, and voicemail. Priced around $100-130 AUD per handset (check current pricing), it is the default recommendation for a small team needing one or two mobile handsets on their hosted PBX system.The Yealink W76H adds Bluetooth connectivity (allowing you to pair a wireless headset to the DECT handset) and a slightly larger 2.4 inch display with enhanced resolution. It targets users who want to use a Bluetooth earpiece while mobile. Priced approximately $120-150 AUD per handset. For most offices, the W73H is adequate; the W76H makes sense for staff who frequently use a headset while handling calls on the move.The W70B base station (required for both) connects via Ethernet, supports PoE, and can handle five registered handsets and four simultaneous calls. It registers with your hosted PBX exactly like a SIP desk phone. Yealink auto-provisioning is supported by major Australian hosted PBX providers including Maxotel.

Grandstream DP Series: DP722 and DP730

Grandstream's DP series offers a cost-effective IP DECT alternative with strong feature parity against Yealink at a slightly lower price point. The DP722 is the entry handset (1.8 inch screen, 20 hours talk time, basic SIP feature set) pairing with the DP752 base station. The DP730 is the mid-range handset with a larger 2.4 inch colour screen and 20 hours talk time.The DP752 base station supports five registered handsets and four simultaneous calls, with PoE support. For larger deployments, the DP755 extends this to ten registered handsets and ten simultaneous calls on a single base -- a meaningful difference if you have five or more staff who might call concurrently. Grandstream DECT is supported by major Australian hosted PBX providers via SIP configuration, though auto-provisioning support varies by provider. Check with your provider before purchasing.

Snom and Poly DECT Options

Snom is a German manufacturer with a strong reputation in the European market, increasingly available through Australian distributors. The Snom M-series (M65 handset, M900 base) targets the business market with emphasis on audio quality and build durability. The M900 base supports up to eight handsets and eight simultaneous calls, making it a useful stepping stone between entry-level (five-handset) and full enterprise multi-cell deployments. Snom DECT pricing is marginally higher than Yealink and Grandstream equivalents but offers a robust alternative if preferred by your provider or IT team.Poly (formerly Plantronics) produces DECT headset systems (the CS540 and Voyager series) rather than full DECT phone systems. These wireless headsets connect to a traditional desk phone or PC and allow the user to move around within headset range. They are not IP DECT systems -- they do not register with a hosted PBX independently -- but they are a legitimate use case for staff who want wireless freedom at a single workstation. If you need a standalone DECT handset that replaces a desk phone, look at Yealink or Grandstream instead.

What Most Businesses Get Wrong When Buying DECT Phones

Three mistakes account for the majority of DECT purchasing problems in Australian SMBs.

Mistake 1: Buying DECT Handsets Without a Compatible Phone System in Place

IP DECT handsets are handsets. They are the last step, not the first. A Yealink W76H sitting in a box without a SIP account to register to is useless. Before you order a single handset, you need: a hosted PBX provider (who gives you SIP credentials and supports Yealink or Grandstream provisioning), a phone system plan, and ideally a test desk phone working on your service. Then you add DECT handsets. Buying handsets first and figuring out the service second almost always results in compatibility problems, configuration friction, or discovering that your ISP's bundled VOIP service does not support SIP registration at all.See our guide to choosing a VOIP phone system for small business and use the Phone System Sizing Wizard to confirm what you need before buying hardware.

Mistake 2: Confusing the ISP ATA Port With a VOIP-Capable Port

The green phone port on your NBN modem is an analog telephone adapter (ATA) port. It converts your ISP's hosted VOIP service into an analog signal for a standard telephone. It looks like a phone port. It acts like a phone port. But if you plug a DECT base station's Ethernet cable into your router and try to register it with the service behind that green port, it will not work. Those are two completely different systems.This is the single biggest source of confusion for DECT buyers in Australia. The ISP-controlled ATA service behind the green port is almost always locked down: the ISP programs the SIP credentials into the modem firmware, and they are not accessible to you. Even if you called your ISP and asked for your SIP credentials to use with a Yealink, in most cases they cannot or will not provide them. You need a dedicated business VOIP service from a provider like Maxotel to get SIP credentials you can actually use with an IP DECT system.

Mistake 3: Undersizing Base Station Capacity

A base station that supports five registered handsets but only four simultaneous calls will drop calls when all five staff try to call at once. This is rare but predictable in a busy service environment, reception desk, or a medical practice where multiple clinicians take calls simultaneously. Before purchasing, calculate your peak simultaneous call requirement -- not just your headset count -- and choose a base station with adequate capacity, or deploy two base stations if needed.

Australian Considerations for DECT Deployment

NBN and VOIP Call Quality

DECT phones on an IP DECT system are only as good as the underlying VOIP call quality. If your NBN connection has high jitter or packet loss, call quality will suffer on DECT handsets exactly as it would on a wired SIP desk phone. Before deploying IP DECT, confirm your internet connection meets the requirements for your expected call volume. As a baseline, each simultaneous VOIP call requires approximately 100 Kbps upload and download bandwidth using the G.711 codec. Four simultaneous calls need roughly 400 Kbps dedicated bandwidth -- easily achievable on most NBN plans, but worth confirming.Use the VOIP Cost Calculator to check bandwidth requirements for your team size, and review our VOIP call quality guide for NBN-specific optimisation steps including SIP ALG disabling and QoS configuration.

PSTN Shutdown and Analog DECT

Australia's copper PSTN network was switched off progressively from 2022 and is now effectively decommissioned in NBN-serviced areas. Any business still relying on an analog DECT phone connected to a copper landline line has already been or will be migrated to their ISP's NBN voice service (via the ATA port) whether they realise it or not. If you have not consciously chosen and configured a business VOIP service, you are on the ISP default service -- which is fine for receiving calls, but lacks all the features of a proper phone system.

Number Porting and DECT Deployment

When switching from an ISP voice service to a dedicated business VOIP provider, you will likely want to port your existing number. Australian number porting typically takes 5-10 business days for standard geographic numbers and longer for 1300 or 1800 numbers. During the porting window, your existing number stays active on the old service. Plan your DECT deployment timeline to align with the port completion -- configure and test your IP DECT system on a temporary number first, then the ported number takes over automatically once the port completes. See our PBX guide for more on how number porting works with hosted phone systems.

Power Outage Considerations

IP DECT base stations require power and a working internet connection to operate. Unlike a traditional PSTN phone, an IP DECT handset will not work during a power outage unless your network equipment (router, switch) is on an uninterruptible power supply (UPS). This is worth factoring into deployment planning for businesses where call availability during outages is critical -- medical practices, emergency service adjacent businesses, and similar. If 000 access during a power outage is required, a battery-backed analog phone on the ISP ATA port (or a mobile phone) provides backup.

Choosing the Right Provider Before You Buy Handsets

The single most important step before purchasing any DECT hardware is confirming your hosted PBX provider supports the model you are considering. Auto-provisioning -- where the provider sends configuration to the phone automatically when it comes online -- dramatically reduces setup friction and support calls. Yealink DECT systems (W70B base, W73H and W76H handsets) have the broadest auto-provisioning support among Australian hosted PBX providers. Grandstream is well supported but coverage varies by provider.Contact your provider before ordering hardware. Ask specifically: does your provisioning system support Yealink W70B (or your chosen base station model)? Can you pre-configure the handset for me? What SIP credentials do I need to enter manually if auto-provisioning is not available? The answers will shape your hardware choice more than any spec sheet.If you do not yet have a hosted PBX provider, read our comparison of hosted PBX versus on-premise PBX and our overview of the best VOIP phone systems for Australian small business. Choosing the right service first will determine which handsets make sense.

Setting Up an IP DECT System: What the Process Looks Like

For a business deploying IP DECT handsets with a hosted PBX provider, the setup process has five steps.Step 1: Confirm your hosted PBX provider supports your chosen DECT base station model and can provide SIP credentials (or a provisioning URL if auto-provisioning is available).Step 2: Connect the DECT base station to your office network via Ethernet. Position it centrally for the coverage area you need. If using PoE, your switch powers the base station automatically. If not, connect the optional power adapter.Step 3: Register the base station with your hosted PBX. If your provider supports auto-provisioning (Yealink DECT is widely supported), this is as simple as entering the provisioning server URL into the base station's web interface. If configuring manually, enter the SIP server address, SIP username, and SIP password as provided by your hosted PBX provider.Step 4: Pair handsets to the base station. Each handset is paired via the base station's registration mode. On the Yealink W70B, this involves pressing the FIND/INTERCOM button on the base to enter registration mode, then navigating to the registration menu on the handset. The process takes under two minutes per handset.Step 5: Test calls -- both inbound and outbound. Confirm call quality, hold and transfer functions, and that voicemail works correctly. Walk the coverage area to confirm range is adequate for your building.The entire process for a single-base, three-handset deployment typically takes 30-60 minutes for someone with basic networking familiarity. Most hosted PBX providers offer guided setup support -- Maxotel, for example, provides configuration assistance as part of their onboarding -- so you do not need to have IT expertise to get a DECT system running.

When DECT Is the Right Choice (and When It Is Not)

DECT phones are the right choice when staff genuinely need to be mobile while on calls. Warehouses, retail floors, clinics, workshops, and small offices where the same person covers reception and walks to other rooms are all good use cases. The wireless range, battery life, and call quality of a modern IP DECT system is excellent for these environments.DECT phones are not the right choice when the user sits at a fixed desk all day. A wired SIP desk phone -- Yealink T-series, Grandstream GXP-series -- provides better audio quality, a larger screen, more programmable buttons, and lower latency than an equivalent DECT handset at a similar or lower price. See our comparison of the best SIP desk phones for Australian business for desk phone recommendations.DECT phones are also not a substitute for a proper VOIP setup. A consumer DECT phone on your ISP's ATA port gives you one line, no PBX features, and no ability to scale. If your business needs hold music, call queuing, after-hours routing, or multiple simultaneous calls, start with a hosted PBX provider and then add IP DECT handsets. The phone comes last.

Your Next Steps

Before you buy any DECT hardware, work through this checklist:1. Confirm you have (or are getting) a hosted PBX or on-premise phone system with SIP credentials. If you are currently using the green port on your ISP modem, you need to address this first. Visit Get a Recommendation to discuss options.2. Confirm your hosted PBX provider supports your chosen DECT base station model and can assist with provisioning or configuration.3. Calculate your peak simultaneous call requirement (not just your headset count) and choose a base station with adequate capacity.4. Check the coverage area you need. For a single open-plan office, one base station is usually enough. For a multi-storey building or large warehouse, plan a multi-cell deployment.5. Decide whether you need Wi-Fi flexibility (Yealink W76H adds Bluetooth for headset pairing) or whether the standard W73H meets your needs.6. Use the Phone System Sizing Wizard to cross-check your seat count and call volume against the right system configuration before ordering anything.7. Order a base station and a single handset first. Test fully before ordering additional handsets.

DECT cordless phones are a common choice in hospitality for housekeeping and floor staff who move around the building. For the full context on phone system setup in hospitality environments, see VOIP for Hospitality Australia.

Can I use a DECT phone with my ISP's NBN voice service?

Yes, but only an analog DECT phone connected to the analog port (green port) on your ISP modem. Consumer DECT phones (Panasonic, Uniden, Oricom) plug into that port via an RJ11 connector. Business IP DECT phones (Yealink W-series, Grandstream DP-series) connect via Ethernet to a SIP-based hosted PBX service -- they cannot use the ISP's ATA port. If you want an IP DECT system, you need a dedicated business VOIP service with SIP credentials, not the ISP's bundled voice service.

How many handsets can I pair to one DECT base station?

It depends on the base station model. The Yealink W70B supports five registered handsets and four simultaneous calls. The Grandstream DP752 also supports five handsets and four simultaneous calls. The Grandstream DP755 scales to ten handsets and ten simultaneous calls. For larger deployments with more than ten users, multi-cell DECT systems (Yealink W80B, Grandstream multi-base) allow multiple base stations to work together with handset roaming.

Do IP DECT phones work with all hosted PBX providers?

IP DECT phones use the standard SIP protocol, which means they are theoretically compatible with any SIP-based hosted PBX. In practice, the important question is whether your provider supports auto-provisioning for your chosen model. Yealink DECT systems have the broadest auto-provisioning support among Australian hosted PBX providers. Grandstream is well supported but check with your specific provider. If auto-provisioning is not available, manual SIP configuration works but requires entering server address, username, and password via the base station's web interface.

What is the range of a business DECT phone?

Manufacturer specifications for IP DECT base stations typically quote up to 300 metres in open outdoor conditions. Real-world indoor range is much lower: expect 30-50 metres through concrete walls and floors in a standard office, or up to 100 metres in an open warehouse environment. For coverage beyond a single floor or room, deploy multiple base stations. Yealink's W80B multi-cell system and Grandstream multi-base configurations allow handsets to roam between base stations without dropping calls.

How long does the battery last on a business DECT handset?

Yealink W73H and W76H handsets offer up to 30 hours talk time and up to 400 hours standby. Grandstream DP722 and DP730 offer up to 20 hours talk time and 250 hours standby. In real-world office use (a mix of calls and idle time on the cradle), most users find they can go several days between charges. Placing handsets on the charging cradle when not in use -- as most desk workers naturally do -- effectively eliminates battery concerns for typical office usage patterns.

Do I need a separate phone line for each DECT handset?

No. In an IP DECT system, the base station holds the SIP account (or accounts) and each handset shares that account. Multiple handsets can receive the same incoming calls (ring all or ring in sequence), and the base station handles simultaneous call routing. You can also configure individual handsets with their own SIP accounts if needed -- for example, if each person has their own extension. Your hosted PBX provider configures this as part of your phone system setup.

Is a DECT phone better than a Wi-Fi softphone for mobile staff?

For most Australian office environments, IP DECT provides more reliable call quality than a Wi-Fi softphone on a mobile device. Wi-Fi softphones (apps on smartphones or tablets) are dependent on the quality and consistency of your Wi-Fi coverage, which is often patchy in warehouses and multi-room buildings. DECT uses a dedicated radio frequency separate from Wi-Fi, is designed specifically for voice, and provides predictable battery life and call quality. For staff who primarily work on mobile devices and make occasional calls, a softphone is adequate. For roles where call handling is a core activity, IP DECT is the more reliable option.
