Add Voice Route and Online Voice Routing Policy
The Service Provider SBC is added as a PSTN SBC to the Service Provider M365 Teams tenant. This enables Live Platform customers to connect calls to their Service Provider Carrier or to their own Carrier (BYOC), traversing the Service Provider SBC, via the Hosted Direct Routing model using the Derived trunk feature.

Hosted Essentials customers can only connect calls (configure SIP Connections) using the Derived PSTN trunk.
