A Titanium 3CX partner, and one of the top six in Australia
Titanium is 3CX’s highest partner tier. In practice it means our engineers are certified on the platform, we escalate directly to the vendor rather than through a distributor, and we see fixes before they are general. The 3CX platform is deeply configurable, so the phone system works the way your business already works rather than the other way around.
One platform for calls, chat, video and web meetings
We do not rely on a bulky phone system at your premises — the platform is entirely in the cloud, backed up and always online. Mobile apps, web apps, desktop apps, and of course the handset on the desk.
SIP trunking and numbers, included rather than sold separately
The lines and numbers that connect your phone system to the outside world come as part of the system. We port your existing numbers, provision the trunks, and size the channels to how your business actually calls — so there is one supplier, one bill, and nobody pointing at anybody else when something needs fixing.
It talks to the systems you already use
Calls can pop the right customer record, log themselves against the right ticket, and click to dial from inside the tools your team already has open. We integrate with common CRM and ticketing platforms, and where there is an API we will usually make it work.
Proactively managed, from Adelaide
We do not wait for you to notice. The system is monitored, patched and reviewed by the same local team that installed it, and when something needs attention you generally hear it from us first.

Reading on this
Teams calling is not a phone system
Microsoft Teams is an excellent way for colleagues to call each other. That is a different problem from running a business phone number, and the gap catches people out.

Moving your phone system to the cloud without an outage
Number porting is the part that goes wrong, and it goes wrong in predictable ways. Here is the sequence we use so the phones never stop ringing.
