[cisco-voip] CUCM and cube sending weird packets?

['Jonatan Quezada']

What would change this this packet 20 percent of the time? We are trouble
shooting the last ghost issue after SIP cutover.  I was on the horn with
the provider and CiscoTAC and we see this for good and bad calls: any
reason why centuryLink's stuff would not recognize this update from us, or
possibly the (Cube,CUCM) sending last wierd packet of update one in five
times which causes the call to drop

Bad calls the last invite has m=audio 20674 RTP/AVP 0 a=X-cisco-media:umoh
a=ptime:20
a=rtpmap:0 PCMU/8000 and no RTP from the cusotmer PBX

and good calls has m=audio 20650 RTP/AVP 0 101 a=ptime:20 a=rtpmap:0
PCMU/8000 and good RTP from the PBX


Last invite on good call from the customer
