3CX VoIP Provider

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

C2 Communications’ SIP Trunks were the first 3CX supported SIP services in Sydney 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.

  • Fantastic support and staff, they truly understand what it means to be a business partner.


  • We’ve had these guys looking after our phone and I.T. needs at work since 2010 and they’ve always been fantastic. Service is always spot on and they’ve never let us down. I won’t even speak to any other company trying to poach our business.
