I have no audio except if I set an allowed codecs string for each device (g722&alaw&g729).
The default audio codecs checked on General SIP settings is not applied.
Is this the expected behavior ?
I remember having found the advice long time ago when I started creating PJSIP extensions in a mixed envt mainly CHANSIP, a couple of PJSIP.
D&U mode set. Checking if it does work for me.
