Log in to the CloudSBC portal and go to the Sprachgateways menu.

Select the innovaphone PBX voice gateway. This was created automatically when you created your CloudSBC account using the Connector App for Microsoft Teams Phone on your innovaphone myApps platform.
Now enter the SIP domain. This should match the SIP domain in the innovaphone PBX.
For the SIP proxy, enter the host name or the fixed external IP address with port number for SIP/TLS on the innovaphone Reverse Proxy. This port can be chosen freely, but must match the port forwarding in your router. We recommend port number 5071.
The PBX password was set when the innovaphone PBX was set up and is required to register Microsoft Teams subscribers as virtual IP phones in the PBX.
Save your configuration.
