3CX VoIP Provider

We are proud to be the first 3CX Titanium Partner in Brisbane and throughout Australia.

C2 Communications’ SIP Trunks were the first 3CX supported SIP services in Brisbane and Australia over 10 years ago. The strength of our VoIP services has been maintained ever since, with a strong record in excellent service delivery and commitment to both platforms. Our efforts have continued to be recognised in recent years, with our unbroken run of consecutive years as a 3CX Titanium Partner making us one of Australia’s most preferred VoIP providers.

Finding a VoIP provider that feels right should take time and cost you money, C2Communications has for over 20 years been building trusted client service and solutions.

See why C2 is right for you

  • C2 Communications installed our 3CX phone system and it works seamlessly between our several sites. The changeover to using SIP lines has proven to be extremely cost effective. After the installation, our staff were trained on how to manage the system internally and we are particularly impressed with its reliability and functionality. It’s definitely been a positive move for our business.


  • The technical and professional staff at C2 Communications have been extremely helpful in getting our entire IT&T networks to work smoothly and effectively across several Melbourne offices. With the high volume of telephone calls made, we have certainly benefited economically with the decision to install 3CX. The IT team has been highly responsive and we would not hesitate in recommending both their IT services and VoIP solutions.
