SIP Trunks for Your Existing Phone System

Keep the PBX and handsets your team already uses while replacing older phone lines with internet-based calling. SIP trunks make it easier to add call capacity, keep your existing numbers and update your setup without replacing the entire phone system.

Not everyone needs a new phone system

Plenty of businesses have a PBX that still works, their staff know how to use it and there’s no good reason to replace it. Starting again can be disruptive and expensive.

If your existing system is compatible, SIP trunks can update the service connecting it to the public phone network. You keep the PBX, handsets and numbers you already have while gaining more flexible call capacity and better-supported business calling.

Book a review with SmileTel and we’ll take a practical look at your phone systems, internet, mobile and networks. We’ll identify what’s working and what gaps need to be filled in.

We connect to what you already have

We can connect SIP trunks to many widely used business phone systems, including 3CX and PBX platforms from Panasonic and NEC. If you’re running something less common, we’ll check its compatibility before recommending a move.

You’ll know whether your current system will work, what needs to be configured and whether any hardware changes are required. No surprises when it’s time to switch over.
