To use VoIP.ms with your ScopTEL PBX, in order to receive and make calls you will need to create a Trunk, an Inbound route and an outbound route. You must have your VoIP.ms sub account credential, such as your username and your password. We suggest using the VoIP.ms PoP Server that has the lowest latency between your ScopTEL IP PBX and the VoIP.ms PoP Server. To retrieve our PoP Servers list, click here
