Looks good to me! J What is the speed of the link? Looks like a 384Kb/s FT1. Is this a Point to Point T1, or a DIA (Dedicated Internet Access) T1? How saturated is the link during congestion (you can do a "show int ser0/0/0" during congestion and look at the "rxload" and "txload" to get an idea)? I'm assuming it's using HDLC based on the lack of extra config on the serial interface. What does the output of "show policy-map interface serial 0/0/0" give you during times of congestion? Any drops? Is it matching traffic correctly?

I am no cisco expert (not even a CCNA)...but... I am trying to configure quality of service for voice over IP.
