Stale SIP Sessions

L2 Linker

Hello all,

 

We seem to have an issue with sip sessions being stuck in the session monitor for weeks and sometimes months.  There have been instances, albeit extremely rare, where it prevented new sessions from being formed on a sip trunk we were testing (it's being moved off of the firewall for production).  Once I cleared the stuck session we were able to make calls again.  The phones themselves are Polycom.  I have ALG turned off on all firewalls and the sip application timeout has been adjusted from 3600 seconds to 20 seconds.  The timeout adjustment seemed to help but I still see stuck sessions every so often.  Anything else that can be checked or adjusted?  I'm not much of a phone system expert so this is a little out of my realm.

Hey All, same issue for us as well.  We have the sip session timeout less than 1 hour, but we still get the same issue.  For me, it seems to occur after a FW failover (we have active/passive).  And the old sessions sits there for the day or longer if its not noticed, and then prevents calling.

Did you ever find a solution to this?
