Whether you need a POE switch for your VOIP phones depends on one thing: whether your phones include a power adapter. If they do, you probably do not need a POE switch. If they do not, you do.
3 June 2026VoIP phone systems are internet-connected services, and like any internet-connected service they attract unwanted attention. The specific threats are well-understood and the mitigations are straightforward. But most Australian businesses running VoIP have not implemented even the basics. This guide covers what actually threatens a VoIP system, what the consequences look like, and what to do about it.
27 May 2026Traditional fax and VoIP do not play well together. The reason is technical and worth understanding: it explains why your fax machine worked fine on the PSTN copper line and produces unreliable results over your NBN-connected VoIP service. Here is what is happening, when T.38 fax-over-IP helps, and what Australian businesses actually use instead.
26 May 2026If someone told you that you need a phone system and you are not sure what that means, this guide explains it from the beginning -- no jargon, no assumptions.
22 May 2026If you've been researching a new business phone system and keep seeing both 'VoIP' and 'SIP' mentioned as if they're the same thing, here is the plain-English explanation. VoIP means phone calls made over your internet connection instead of the old copper phone line. SIP is the specific technical standard most business phone systems use to make those calls. For most businesses, the distinction matters when buying hardware or choosing a provider.
22 May 2026VOIP is the right choice for most Australian businesses. But not all of them. This article is the honest counterpoint: the specific situations where VOIP introduces more risk than it removes, and what to do instead.
21 May 2026An NBN outage takes your VOIP phone system offline. For a business that relies on inbound calls, that is lost revenue sitting in a dead phone. A 4G or 5G failover connection can bring calls back in under a minute with the right setup.
20 May 2026If you're a small Australian business trying to work out whether you need a proper phone system or whether your current mobile and NBN bundle is enough, this guide gives you the answer. A hosted PBX (phone exchange managed by a specialist company) gives you the same call handling capabilities as a large company, without owning any hardware. For most businesses with 2 to 30 staff, it is the right starting point.
19 May 2026Hosted VOIP is the right answer for most Australian small businesses. But most is not all. For businesses with 30 or more seats, strict data sovereignty requirements, or a poor NBN connection, an on-premise PBX can still deliver better value and more control than a monthly hosted plan. This guide gives you the honest comparison.
18 May 2026If your business is missing messages because staff have to dial in to check voicemail, or messages sit unchecked for hours, voicemail to email fixes that. It sends each voicemail as an audio file to a nominated email address the moment it's left. This guide covers how to set it up on common Australian phone systems, including Maxotel and 3CX.
8 May 2026FreePBX is the most widely deployed open-source PBX in the world. Setting it up correctly for an Australian business takes more than following the generic documentation. Here is the AU-specific setup path.
7 May 2026Getting the number of SIP trunks wrong costs money in one of two ways: too few means customers get busy signals at peak times, too many means you are paying for capacity sitting idle. Here is how to size it correctly.
30 April 2026If your IT company manages your phone system and you're paying more than expected or missing features you were told were included, this guide covers what managed service providers typically don't volunteer when setting up business VOIP (phone calls made over your internet connection, instead of the copper phone line). None of this is unique to bad providers. It is the result of how MSP pricing models work, and knowing it in advance means you can ask the right questions.
20 April 2026If your business uses a cloud phone system and you are worried about what happens during a power outage, this guide covers the three ways to keep your phones working. VOIP (phone calls made over your internet connection) relies on your modem and router staying powered, not just your internet connection staying up. Most businesses do not need an expensive uninterruptible power supply. The right solution depends on your NBN connection type and whether your phone system has a mobile app fallback.
20 April 2026Cloud PBX is a business phone system where the software runs on a provider's servers, not in your office. You access it over your internet connection and your provider manages everything. This guide covers how cloud PBX works on NBN, what it costs in Australia, and who it suits -- and who it does not.
31 March 2026If your business has switched to a cloud phone system (where calls go over your internet connection instead of the copper phone line) and you're not sure whether your phones can still call 000, the short answer is yes. But there is one critical difference from a traditional Telstra landline that most businesses miss when they switch. This guide tells you exactly what to set up and check.
30 March 2026If you have existing analogue handsets that you want to keep when switching to a cloud phone system, an ATA (Analog Telephone Adapter) lets you connect them without replacing the hardware. Most businesses switching to VOIP (phone calls made over your internet connection, instead of the copper phone line) don't need to replace their existing desk phones. This guide covers which ATAs work with Australian VOIP services, what they cost, and how to set them up.
30 March 2026Ring groups, hunt groups, and call queues all distribute incoming calls, but they work differently and suit different situations. Pick the wrong one and you will lose calls or frustrate customers.
30 March 2026VOIP is how almost every business phone call is made today. If you have an NBN connection, you are almost certainly already using it.
30 March 2026If you've switched your business to a cloud phone system and want to understand how calls actually get from your phone to the person you're calling, this guide explains it in plain English.

30 March 2026If you have come across the term PBX and were not sure what it meant, you are in good company. Most small business owners encounter it when looking at phone systems and nobody explains it clearly. In plain terms, a PBX is the system that manages your business calls. It routes calls to the right person, handles hold music, manages after-hours messages, and runs your auto-attendant. This guide explains how modern cloud PBX works, whether you need one, and what the NBN means for your setup.
27 March 2026If your business phone calls are unreliable and you're not sure whether your NBN connection is part of the problem, this guide answers that. Australia's NBN comes in five different types and they don't all perform equally for business phone calls. The type at your address directly affects call quality, reliability, and how many calls you can run at once.
27 March 2026If your business phone calls are choppy, robotic, or dropping out, this guide diagnoses the most common causes and shows you how to fix each one. Call quality problems on cloud phone systems are almost never caused by the phone provider. The cause is almost always one of three network issues at your end, and all three are fixable without calling a technician.
27 March 2026Your guide to every type of business phone system available in Australia in 2026: hosted cloud PBX, on-premise PBX, Microsoft Teams Phone, ISP ATA service, and DECT systems. Covers pricing, features, sizing, NBN requirements, and how to choose an Australian provider.
