[jitsi-dev] How to play sound in call



I trying to create simple AVR with Jitsi.
It will call programmatically then play a sound file with question and
recognize callee DMTF code of response (1 - yes, 2 - no).

Thus I have two questions:
1. How can I play sound in current call?
2. How can I recognize callee DMTF code?
