Not really, here the PSTN call is happening and the web page starts to capture audio.
In that case, audio capture will fail as the PSTN call has higher priority.
Audio capture can succeed through getUserMedia once the PSTN call is finished.

An improvement would be to mute the audio capture until the PSTN call is finished, at which point we could potentially unmute the audio capture.
This would require us to be notified when the PSTN call ends.
