Dear all,
I have a question about session timers. I have one of my installations
(* 1.6.2.7) where all SIP calls get stuck, like this:
cs4wall*CLI> sip show channels
Peer User/ANR Call ID Format Hold

Strange thing is, I enabled sip session timers=originate, and
rtptimeout, but this doesn't seem to do anything.
I noticed that a "sip show channel xxx" while the call is actually up
says:
> Session-Timer: Active
> S-Timer Interval: 1800
> S-Timer Refresher: uac
> S-Timer Expirys: 0
> S-Timer Sched Id: 2267
> S-Timer Peer Sts: Active
> S-Timer Cached Min-SE: 90
> S-Timer Cached SE: 1800
> S-Timer Cached Ref: auto
> S-Timer Cached Mode: Originate
A few seconds later, when the phone actually hung up, for the same sip
channel I get:
> Session-Timer: Inactive
This seems strange to me. Any ideas?
Thanks a lot.
Leo
