With the evolution of the telecom industry, CallTower has grown into a unified communications, collaboration and contact centre solutions provider; changing the way people communicate around the world.

Our mission is to enable people to easily connect and get work done.

CallTower truly delivers service quickly and efficiently from answering the phone to taking the service request to initiating repair and following up to be sure the issue is resolved. It would take other providers hours if not days to do many of the requests that CallTower handles is literally minutes. I am relieved and impressed and very proud to work with CallTower

We migrated our on prem Cisco telephony system to Calltower’s Cisco solution. This included 22 offices across the globe. The migration went perfectly and the Calltower team was amazing to work with. We’ve been on their system for about a year now and we’re very pleased with the service.
