Mon Mar 25 13:32:48 EDT 2019

Non working call shows G711u and a, working call shows only a.  there is
also a difference of the /1 at the end not sure what that indicates.

a=rtpmap:0 PCMU/8000/1

a=rtpmap:8 PCMA/8000

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

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.
