SIP Trunking: All the advantages of the cloud, on your timeline

Squeeze more life out of your legacy PBX

Jumpstart your cloud journey with a hybrid solution

You don’t need to rip and replace your entire phone system to reach the cloud. Masergy leverages Session Initiation Protocol (SIP) trunking, enabling you to deploy VoIP services both on-premise and in the cloud. In this model, you get a phased approach that allows you to migrate to the cloud one location/system at a time, progressing toward a fully hosted model only when your PBX systems are ready to be retired.
