Jeremy,

Do you have localnet and externaddr set?  Those are part of the NAT settings I was referring to. Asterisk thinks that your phones on the local network are behind NAT though when they are not.

You are correct that this is the recommended setting for 'nat='.

> 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

> 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.
