Summary:                    RTP Timeout is flawed
Description: 
The sip.conf configuration rtptimeout=XX only considers one way, not both.
Suppose the caller is silent for more than XX seconds, on mute, while his
mother issues a long speech. The call drops. This function must consider
audio both ways, and only if there is silence in both channels, drop the
call.

In my particular case, if I call to a voicemail where the greeting is
longer than XX seconds, and I simply keep my microphone silent, the call
will drop exactly at XX seconds, invalidating the whole thing.

---------------------------------------------------------------------- 
Asterisk 1.4 does not support session timers. As for your comment about
rtptimeout not working under pretty normal conditions - these aren't pretty
normal conditions. There's a reason you are the first person to bring this
up and that is because most setups do not use VAD or silence suppression
and continue to send packets even while muted. In those more normal
conditions rtptimeout would operate perfectly fine as intended.
