Develop a push to talk capability for the 1% of soundcard that are still
half-duplex would not be very efficient. Unfortunately I have very very
little time to spend on linphone and I have to carefuly choose the

I don't think so. However if somebody does it, I'll merge the patch.

You're welcome. The 1 second audio delay is due to the soundcard (or the
driver). Try an alsa driver (if exist).
