Hi All,
We encountered an issue wherein the call was being disconnected every 30 mins during conference call.
As per checking, there is a existing bug on CUBE:
CUBE: Session refresh via sip UPDATE is consumed by CUBE CSCty36625
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCty36625/?referring_site=bugquickviewclick
The current setting of SIP Session Timer under CM Service Parameter is set to 1800 by default or equivalent to 30 mins.
Here is the current config of the CUBE model 3945 under voice service voip:
=============================================

!
=============================================
My question is, can we upgrade the IOS version of the CUBE instead of applying the command as suggested on workaround however, the current version of the IOS is not listed on the known affected release. The current IOS version of our CUBE is 15.4.3M3. What IOS version should we use to fix the issue.
Thanks
Josh
