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

I know SP CUBE on ASR can do this but I don't think ISR CUBE or ASR Enterprise CUBE does it. From what I can see, ISR CUBE can only send a trap if the configured MOS score falls below a certain threshold but no action is taken. With the Acme Packet SBC I can do real time MOS scoring to CDR's and/or view the MOS score per-call in the Web GUI ladder diagram. If the path to a far-end IP peering point causes the MOS score to fall below the configured threshold the Acme Packet SBC will route new calls to a secondary or tertiary path automatically (called QoS Routing) and send an alarm. For calls coming into the SBC from the peering point on the bad path the SBC sends a SIP 503 back to the carrier so they re-route to the secondary data center.
