[cisco-voip] SIP phones & CMR

[Ryan Ratliff (rratliff)]

Grab the CCM traces and see if the phone is even sending them.

Also make sure the Call Diagnostics service parameter is enabled on all servers.

The only data I see in the CMR are the IP addresses of the endpoints and the payloadcapability.    All the packets sent/received, jitter, latency, etc values are always just 'null'.

Sample below.

What specific data are you looking for?  The newer phones have dropped MOS and Q-Factor subjective ratings in lieu of concealed seconds and severely concealed seconds.

You won't see any raw MOS values reported by newer phones.

I've noticed on the last few systems I have worked on that the SIP based phones are not showing any CMR data in the CUCM CAR system.

This is happening on atleast 8945s & the new 7841s.   Also I have noticed that the Jabber for Windows phones aren't reporting it either.

This is happening for both on-net IP phone to IP phone calls and also off-net SIP calls to CUBEs (then to SIP Provider) and also off-net calls via CUCM SIP trunk to Cisco 29xx PRI gateway.

Is there something I need to turn on for the CMR data to be generated ?  Or is this just not supported in the SIP phones / CUCM ?
