There has been some excellent suggestions in this thread. I just want
to add one. Sometimes a SIP packet can get lost or a phone rebooted
without closing a call properly. Then the call will just stay open
forever. You can solve that with rtptimeout=3600 or something similar
in sip.conf. Obviously it only works when the rtp stream is actually
going through Asterisk, and it will also kill the call if a Snom phone
turns the microphone off for an hour (Snom phones do silence
suppression unconditionally when you press the mute button).
Still, even with those limitations it works nicely for us. At least as
a stopgap until Asterisk gets TCP-support for SIP.

I know this post s old but I will add my 2c. In sip.conf you can use
silencedetecthangup=x. Have a look at:
