In my last question I showed how I had configured CBWFQ for video traffic,
with a priority queue for the video and fair queueing with WRED for all
other traffic.

If my goal is to assign video or voice traffic to a priority queue, why
could I not simply do the following:

Rtr(config-if)# ip rtp priority 3230 3235 312
Rtr(config-if)# fair-queue
Rtr(config-if)# random-detect

Would this not accomplish my goal without the use of classes, ACLs, and
policy maps?  If I did it this way, could I also configure FRF.12
fragmentation and interleaving on this same interface?

I've been deeply researching this for a couple of weeks now, and it seems
like the more I understand Cisco's QoS configuration options, the more
confused I get.  Just when I think I have a plan of attack, i rethink my
choices and start second guessing myself.

Our network consists of about 90 branch routers that will all have voice
traffic, and four branches that will have video conferencing traffic as
well.  Each branch router has a frame relay connection with a minimum of
three PVCs with at least one PVC at each branch carrying voice/video traffic
along with other data.  Given this scenario, any hints/tips/suggestions
would be greatly appreciated.  I currently have  CBWFQ w/ LLQ running at one
branch and it seems to work just great, but I'm still not sure that I'm
making the best configuration choices.

Thanks again, as always...

John
