CUCM sends INVITE after 900 sec http://developer.cisco.com/c/message_boards/find_thread?p_l_id=&threadId=5029144 2013-05-20T05:06:02Z 2013-05-20T05:06:02Z David Staudt http://developer.cisco.com/c/message_boards/find_message?p_l_id=&messageId=5039132 2012-01-21T00:20:48Z 2012-01-21T00:20:48Z

cause=86 looks to be Network Timeout, so I agree the SIP session refresh mechanim mentioned above is likely the root cause.  I guess you can either modify the recorder side to interop with the way UCM does this refresh, or modify the timer so that in practice it never occurs (as above.)

Hi, Sounds like interop problems with session refresh. Try changing the CUCM Service parameter "SIP Session Expires Timer". A refresh is sent after half this time, and the default is 1800 sec. I have changed this to 86400 (max) for some customers due to the same reason. Kind regards, //Dan

Hello, which is the version of your call manager? what is the reason of BYE in wireshark? Best regards Rasheed

Hi,   We have built a Recorder that receives calls via a SIP trunk (recording profile) through the IPPhone's built in bridge   It works fine until the call gets to 900 seconds, we receive another INVITE and it looks like our app sends a Trying, then CUCM sends BYE   I could not find this behaviour in SIP docs, is it a keep-alive? Should CUCM send this? What should happen?   This is a wireshark trace from our server, appreciate any feedback!
