80201: No Available Voice Proxy

Example Message: This Service has no compatible Proxy numbers for this Participant. This Service has no available Proxy numbers having voice capabilities. This can happen if you attempted to create a participant in a session for which you did not specify a Mode in a country that does not support combined voice and sms capabilities.

You tried to add a Participant to a Session with a mode that includes voice, but your proxy pool does not include any voice-capable numbers.

Add one or more numbers to your pool that have voice capability.
