> I have regularly (once a week, once per few hundred calls?) been having 
> problems with Asterisk's SIP stack not responding to packets from any of 
> my registered devices.  In the past, I could not tolerate the outage, so 
> i would restart asterisk to make things happy.
> My Asterisk server is currently in this broken state and I can leave it 
> this way for a short while.  Devices are registered to it and I can 'sip 
> qualify peer xxx' - see [^qualify.txt].  notice the console/debug does not show the return packet, but on the network, the device has clearly replied - [^qualify-tcpdump.txt]
> 'sip show peer xxx' all show Status OK [^sip-show-peer.txt]
> but whenever one of the devices tries to make a new call, Asterisk just 
> doesnt respond.  'sip set debug on' shows no packets.
> from the asterisk server (10.1.0.3), i can see one of my phones 
> (10.1.0.111) trying to make a call but Asterisk won't talk back.
