Jeremy Kister updated ASTERISK-22851:
-------------------------------------
Description:
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]
on the network, this shows [^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:
{code}
