Ad-hoc conferencing on UCM 8.6.2 (users disconnected after 30 minutes)

Problem is as follows:  User on a registered phone on the network conferences a remote user on an outside line (cell phone or land line--both tested).  The user on the cell phone/land line is disconnected exactly 30 minutes after the call is nailed up.  This behavior can be reproduced 100% of the time by simply conferencing in any user on an outside line using ad-hoc conference.  Is there a timer somewhere that is configurable?

Thanks!

Are you using ISDN or SIP?

SIP, thanks!

If you have a firewall in between your CUBE or WAN connection I would verify that it is not resetting or re-establishing the connection. Sometimes the sessions are re-established and it can cause these kinds of issues.

We found a SIP timeout parameter in the ASA and adjusted it.  Will monitor and report back results.

Sounds good let us know how it turns out.

That didn't resolve the issue.  I'm going to continue looking for layer 3 interruptions.

It is not due to layer 3.

It is due to SIP timouts, if you search you will find many threads with the same issue, some have found a solution, some don't.
