About Callroute

Callroute is on a mission to unify traditional telephony with cloud collaboration and contact centre platforms, integrating secure, quality calling and advanced voice features all from the cloud. Learn more about our story and where it all began.

Connecting the PSTN to UCaaS, CCaaS or legacy

We believe that people work best when technology doesn’t get in the way. That’s why we built Callroute. 

Callroute seamlessly integrates PSTN calling with your collaboration platform and legacy equipment. Get advanced features deployed without any new hardware directly from our cloud platform.

From an idea to growth.

Where It All Started

Where it all started

Business collaboration tools have transformed how we communicate, but they’ve also complicated our lives. Traditional telephony hasn’t kept up, and having a different platform for texts, calls, file sharing and more dilutes data and confuses access. Particularly in customer-facing environments, these tools simply don’t deliver. 

A Decision Point

A decision point

In early 2020, companies everywhere suddenly changed the way they approach collaboration, both internally and externally. The pressure this placed on disjointed collaboration platforms made us decide that we had to act. We’d identified both a market opportunity and existing technology limitations, and we knew that we had the background needed to help. 

Putting The Technology To The Test

Putting the technology to the test

Callroute is a sipsynergy company — providing systems, technology and solutions to telephony and IT resellers, ISPs, systems integrators and distributors. This background put us in a great position to develop a simple yet flexible integration process. 

Our research showed that Microsoft Teams has become the collaboration platform of choice. In our effort to help centralise business collaboration, we decided to focus our energy on Teams and start building a solution that would work.
