Hi list,
we face a strange behavior on an Asterisk 1.6.2.24: from time to
time, around 5 times a day (time when it happend totaly
unpredictable), asterisk doesn't see incoming INVITE SIP packets,
those being catched by a tshark capture :-(
So incoming calls are CANCELED by other party as they never get an
answer on their INVITE. The problem disappear from itself after few
minutes. The server is not overloaded (it happends also during the
night, early morning, at lunch time, ...)
The server is running since monthes and the problem appears around 5
weeks after (we think looking at history) a maintenance including an
asterisk update from 1.6.21 to 1.6.22
If someone had an idea what could be the source of the problem ...
Thanks.
Forgot to say that our asterisk server is registered as client to the
peer one and both parties have static IP addresses.
Step further: asterisk shows that he is registered but is not: session
expires is set to 1800 sec (Scheduling reregistration in 1785 s)
A tshark capture where xxx.xxx.xxx is our server, yyy.yyy.yyy.yyy peer's
one, 33123456789 called number (peer -> our server). As you see, at
206.663941 asterisk is registering to peer and everything is going smoothly.
Before calls where dropped which means asterisk wasn't registered
despite the fact that CLI 'asterisk show registry' tell it is!
