[cisco-voip] SIp Trunk call failing after PBX upgrade

Mon Mar 25 18:24:06 EDT 2019

we are seeing a similar issues to one of our nodes. we did our during
production, Brave but totally doable. After figuring out that we needed to
point the EM profiles to the node we were keeping up for the upgrade, we
took down the other ucs down, all went well for upgrade. All VM on my ucs
are all done now, but there is this huge jitter issues that has risen from
the ashes of the upgrade. Its as if my media RTP streams are being forked
and the forking is causing the jitter and delay?

I have calls where I lose second of audio but signaling seems fine, Im just
losing a ton of packets between the nodes now that they(the pub and sub)
are load balancing the media resources, or rather seeming to load ballance.

After some dial peer and server group re pointing, all devices finally were
on the one node and we were able to upgrade the UCS, but the other is left
to do. all of my CUCM
