Hi,
You can enable VAD (voice activity detection) and when you stop
talking the stream will stop sending packets, except for periodic
keepalive packets whose rate can be controlled by some compile time
constant, or you can disable keepalive altogether.

Hi,
In my project where I simulate some kind of push to talk, I
need to be able to have no payload in the RTP packets when the
PTT is off. I succeeded to do that by removing the payload in
a custom transport adapter and the transport_send_rtp callback
(but is it the best way to do that?).
Anyway my second need is to change the frequency of RTP
packets when I remove the payload (PTT off). For example:
with audio: RTP frame every 20ms
without audio: RTP frame every 200ms
So I was thinking of dynamically changing the ptime of the
codec in use, but I don't figure out how to do that (again
this may not be the right way to do it, any other suggestion
welcome then).
Could anybody give me an hint?
Thanks.
Thibault
