PABX / SIP trunking
Happy with your phone system? Keep it.
Losing your copper lines does not mean losing your PABX. We convert existing phone systems to SIP lines delivered over NBN or 4G, and where a system is too old to speak SIP at all, we convert the SIP lines back to analogue or ISDN so it can keep running exactly as it does today. You keep the handsets, the programming and the way your team answers the phone.
- Keep your existing PABX and handsets
- SIP delivered over NBN, 4G, or both for redundancy
- Analogue and ISDN conversion for older systems
- Managed by us, not left as your problem
Why keep the system you have
Works with your PBX
SIP trunks that register against the system already sitting in your comms room.
Analogue and ISDN conversion
If your system cannot take SIP, we put hardware in front of it that presents the lines in the form it does understand.
More than one path
Run the trunks over NBN, over 4G, or over both, so a single fault does not take your numbers offline.
HD voice where it is supported
High-definition audio codecs on systems and handsets capable of them.
We do the setup
Our team configures the trunks against your PBX and stays on the line until calls are running both ways.
One local provider
Trunks, the connection underneath them and the support call all come from the same Adelaide team.
When this is the right answer
Not every business should replace its phone system
If your PABX is doing what you need, is not out of support, and your team knows it inside out, replacing it is spending money to end up where you already are. SIP trunking keeps that investment working and removes the part that was actually going away — the copper. When the system does reach the end of its life, moving to a hosted platform is a conversation for that day, not a condition of this one.
- A PABX that still does the job and still has support behind it
- Handsets and programming your team is fluent in
- A site where replacing everything at once is not practical
- A staged plan towards hosted voice, at your pace
Numbers
You keep your numbers
Your existing numbers port across to the SIP service, including main lines and direct dials. We plan the cutover with you, do it outside business hours where that suits, and stay available on the day rather than handing you a reference number.
