Keep your PBX
Already run an office phone system? A SIP trunk plugs straight into it, so there's nothing to replace.
SIP Trunks
Connect your existing phone system to the network
SIP trunks replace traditional phone lines with internet-based lines, so your on-premise PBX can make and receive calls over our network, keeping the hardware and numbers you already have.
What is a SIP trunk?
The modern replacement for phone lines
If you already run a phone system in your office, a SIP trunk is the modern alternative to old analogue or ISDN lines.
Keep your numbers
Port your existing numbers across and carry on as normal, with no interruption to how you work.
Lines over the internet
Calls travel over a monitored internet connection instead of ageing copper lines.
