Cisco: MOS scores on SIP trunk to PSTN

We use SIP for most of our call routing. Right now a typical call path for an off-net call would be two legs: 7945G phone to a Cisco 2811 ISR. Then from the 2811 to the PSTN carrier (XO Communications). I can get MOS scores for the calls leg between the phone and the ISR. What I currently lack visibility on is between the ISR and the SIP provider. I would like to know MOS scores, jitter, loss, latency for the SIP trunk to the carrier. I am using the classic 2811. I'll likely upgrade that in the next year as it's going end of life. Would there be any snmp oids or other means I could monitor the quality of the SIP conversations to the PSTN? If not with the current gear perhaps with a new router with CUBE technology? Thank you. I'm feeling like we have a blind spot.

One thought off-hand would be to use IP SLA on the Cisco router.  Using IP SLA to the IP address of the SIP Gateway.  From this you would be able to get packet loss, jitter and latency.  These values will all be accessible via SNMP.

Here is a good blog that explains the configuration and statistic reporting.
