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

Mon Mar 25 19:13:50 EDT 2019

My issue is not a CUCM upgrade. The other side from the SIP Trunk was the one that was updated (a local in-house development, called Mitrol). The system worked fine before the upgrade, and after that it went bonkers.

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

Hi, guys and gals.

I have a customer with a CUCM 9.0(2) cluster.
It is connected to a SIP PBX via a direct SIP TRUNK (No SBC, CUBE or otherwise). The PBX has four different nodes, all configured in the SIP TRUNK

They claim it was working fine until last Thursday, where they did an upgrade to one of the nodes of the PBX. After that, calls going from PBX to CUCM fail with a 488 Media Not Acceptable error.
They also have tried making calls from one of the not upgraded nodes, with the same error.
I have been looking into the SIP traces, and I see nothing really telling of a problem there.

We reseted the SIP trunk with no success.
I have looked at the región configuration, and all regions are set to the System Default (G722, G711)
I also tried changing the preferred codec in the SIP trunk, with no success.

Following this, I am pasting the SIP messages of a failed call from PBX -> CUCM and a successfull call in the reverse, from CUCM -> PBX.

Can you see if anything is wrong or odd?

Regards,

Ariel.
