C2 Communications connects hundreds of businesses across Australia to uncontended business grade internet services, helping lay the foundations of crystal clear VoIP quality well into the future.

About Broadband


We’ve found through years of experience installing and connecting 3CX Phone Systems and C2 Communications VoIP that a commercial grade un-contended broadband connection is the foundation for excellent VoIP line quality and user experience.

We know your phone system is a key business tool and good call quality is essential. When we set up a new system we configure each router to ring fence the bandwidth required to ensure voice quality is not impacted by other internet traffic.

As a rule, we don’t recommend installing 3CX on consumer grade contended ADSL2 services. Upload speeds on these ADSL2 plans can be variable throughout the day, leading to call quality issues.
