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.

---------------------------------------------------------------------- 
rtpkeepalive actually breaks the compatibility with many switches. I cannot
use it. The calls actually fail in the first few seconds when talking to
many flavos of border controllers and softswitches.

The consequences of rtptimeout=XX are such that if I stop talking and just
listen, like in a conference where many people are in "mute", then the call
drops. This is irrational.
