Traditionally, voice services were handled by the major telcos. A lot has changed. Voice has found its way into the realm of IT. At entire tech, we were incredibly early adopters of VoIP (Voice over Internet Protocol) technology and have grown to be a major service provider of voice services across Australia. Voice doesn’t need to be complicated, but you need a team who understand it thoroughly.


On-Premise PBX (Private Branch Exchange) is also known as an IP (Internet Protocol)-PBX phone system. It is similar to a traditional PBX system that resides at a location, such as a computer equipment room or phone closet. These days, the phone system is the size of a router or firewall. IP-enabled phones are required to connect to the IP-PBX server using a LAN/WIFI/Mobile network. Calls go through VoIP using SIP trunking over your business-grade internet connection. An Asterisk based system is the most affordable option for on-premise PBX due to the flexibility that is offered with open source software.

Hosted PBX or Hosted VoIP, otherwise known as an Internet phone system, is one where entire tech is responsible for housing the IP-PBX as well as handling the technology required to provide the services to the phone system. IP-enabled phones will connect to your network via a LAN/WIFI/Mobile network and the calls and features are handled through an IP-PBX server at our cloud location. We have plans that include access to business-grade features plus all call charges. Hosted IP-PBX have a lower upfront equipment cost, no on-going maintenance costs and is scalable to changes within your business.

Hardware – Handset or not to Handset

At entire tech, we have tried and tested almost every phone from every vendor. We’ve taken the guess work out of what works, what doesn’t, what’s reliable and what’s not. For those who require a desktop phone, we’re best friends with Yealink, Cisco and Polycom. Do we still need a desk phone? Some say there is comfort with having one. Some say that it is a tool of the past. We say that it’s up to you. We can configure your desktop or portable computer so you can talk to the screen, or we can provision your smartphone or tablet, anywhere in the world. We’ll even make recommendations on headsets – mono, stereo, bud style, on ear, full, on ear or both, around the neck – the choice is yours.
