Video calls disconnect after 15 min, dissapear after reeboot ?

[mikaelholm]

Hi, We have many videosystems where calls disconnect after 15 minutes. It looks like the well known SIP timer issue. But if I restart the system, the problem also disapear, but can be back again after a few weeks. Can anyone explain this behavier ?

The systems runs CE8.3.3 and is registred to VCS. I have tried to unregister the systems and then register them again, but that do not make any difference. I dont understand why or how a restart solves the problem if it is a SIP timer issue. I have also seen systems that disconnect after 30 min. When the call disconnects, it is not completely disconnected, the systems still sends media but do not receive anything. Most grateful if someone can explain what is going on.

Kind regards

I had a similar problem. I have a cluster of CMS. when I made a call from my cluster to a third-party video conferencing server, there was a break in 15 minutes or 30. The problem was in SIP packet headers. I changed here: Configuration-Outbound calls. clean field "Local contact domain" a troubled route. as far as I understood, in the header of the CMS gave the domain name , and it was necessary to give the IP address of a particular server. Therefore, the third-party server did not accept requests . sorry for my English

Hi, we are also experiencing this issue, has anyone received any fixes or workarounds, this seems more prevalent when Webex is used as the bridge joining from a SX10

Hello,

One of my customer was having this issue and we rectified some third party switch config issue i did not remember the exact config

but You can collect the pcap from switch port VCS and endpoint (for endpoint you can start extended logging before start of call and download the pcap and logs after 2 3 mins and then again start the extended logging around 13 or 14 mins so that it can capture the drop scenario ) for same you will be having the switch ports pcaps as well and determine who is dropping the connection.

If it is endpoint try to do factory reset ad upgrade to latest firmware and see if it resolves the issue.

I know it will be a long process once you reboot the endpoint and again wait for issue to appear again but it will give you some directions for isolating the problem.

Thanks
