# VoIP trunking and call termination

Phone calls over your internet connection instead of old copper lines (Voice over Internet Protocol, or VoIP). It can help your team keep using a familiar phone system while changing how calls reach it.

## Connect the phone system you already own

Link the phone system you already have to our network (SIP trunking). Your office can keep its existing handsets while cutting line rental, subject to your setup.

## Carry outgoing calls

We carry your outbound calls to any UK or international number (call termination). The available destinations and charges can be discussed for your requirements.

## An everyday example

An office with an existing on-site phone system can keep its handsets and connect that system to calls over the internet. This supports the UK’s move away from traditional copper phone lines.
