We have two SIP trunks, one for Main site and a shadow for our DR site.
When the main site goes down, the call path from outside in is to DR IP2IP Gateway router, to a 3750 router, across a DS3 Point to Point circuit, to a 7206 router, then to our Call Manager server.
The QoS policy would be on the 3725 router to the 7206 router that connects the DS3 Point to Point.
When there is heave traffic on the DS3, the call quality suffers when the Main Site SIP trunk is failed over to DR.
If I wanted to set up a QoS policy for the traffic inbound from IP2IP Gateway (CUBE) to call manager, how would I mark the traffic?
Also, would I also need a policy in the direction of Call Manager to IP2IP gateway for the connection in that direction?
