[cisco-voip] Call quality stats on SIP trunk?

[Wes Sisk]

Robert,

My CUBE contact says:

"sh call act voice is where is look first. Looking at the output below I do not
see much diff. in Tx/Rx packet counts for the two leg. So that looks good.
DSP stats are not relevant as for this call CUBE isn’t even going to touch the
rtp payload (no xcoding/MTP in use.)
A sniffer at the egress leg will give us lot in terms of evidence of what we
are receiving and putting out on the wire.

What exactly is the voice quality issue here? CPU checks out ok ?"

I suspect RTP stats would only be collected if using flow-through rather than flow-around… 

I'm hoping NICK MATTHEWS will chime in on this thread.

So we put the OIDs into our SNMP collector (Nimbus), and even with the
downloaded MIB from Cisco, it appears to not have what I need. I
couldn't get anything useful from the "Active Call" OID
1.3.6.1.4.1.9.9.63.1.3.2 that would let me say, "Ah, the leg of the
SIP call going to my provider has a MOS of 3.2, and the internal leg
is OK at 4.5" (Or r-factor, since MOS can be subjective.) Am I missing
something?
