video call are disconnected after 15 minutes

[Anatoly Fanrus]

Hello,

help me pls, after 15 minutes video call disconnected every time.

My configuration CME86 <-SIP-> CME71 <- SIP-> CUCM7.1.3.

I perform call from caller on CME86 to callee on CUCM7.1.3.

I collected debug logs on CME86 and see BYE message from callee on CUCM7.1.3.

Disconnect cause CC/SIP: 16 /200.

Thanks in advance

Cause code 16 is normal call clearing. Does CME71 see the same BYE from CUCM7.1.3? If yes you would need SDI/SDL traces, w/ troubleshooting traces enabled, from CUCM to figure out why it dropped the call.

Thank you, i cant test it now on CME71 but i have changed "sip min-se timer" and "sip session expire timer" to 3600sec on the CUCM and now it's ok, at least after 20 minutes...

Maybe CME71  is needed in the following command "registrar server expires max .. min ..."

My CME71 is more voice gateway (CUBE) it havent any registered SIP phones only dial-peers.
