Connecting and simplifying telephony

Callroute integrates PSTN calling with cloud collaboration platforms or legacy equipment in minutes.

What is Callroute?

Callroute offers market-leading PSTN integration with UCaaS, CCaaS platforms as well as traditional on-premise telephony equipment. Our unique technology automates deployment via a self-serve portal meaning you can be making calls in just a few minutes. Combined with per channel pay as you go pricing and the concept of floating capacity across trunks and geographies, this enables businesses to reduce complexity and costs significantly.

Integrate existing on-premise voice infrastructures such as analogue equipment and PBX's to create hybrid environments that work seamlessly with your chosen platform.
