I am currently running 20 T1's through a Multi Channel T3 Card in a 7206 VXR Router. The VXR Router has an Asterisk PBX Connected to it through a PA-4E (4 Port 10MHZ) Interface. One of the T1's runs to a remote office and we are having Voice QOS Issues. The traffic on the T1 to the remote office can be very low but we have trouble when a lot of traffic is going through the router to and from all the other T1's. What I need to know is the simplest way to provide Priority to the SIP Packets on the VXR Router. I am currently running IOS Version 12.1(9).
