How it works


VoIP works by moving your existing numbers and lines to operate on the internet and terminate on the PSTN and Mobile network. Usually business numbers are with large carriers, like Telstra or Optus, and are ported to C2 Communications. These numbers are electronically registered to our carrier grade data centre to manage high volumes of inbound and outbound call traffic at excellent speed and quality.

Customers typically save 50% when moving from traditional telecom providers.

A C2 Communications VoIP based Phone System replaces the traditional physical PBX with an application hosted on a regular computer or server. IT support teams familiar with this set up can easily manage either hosted or on-premise solutions.
