If it is just voice that you want to prioritize, I would use the ip rtp
priority command. This is because as soon as the voice packet enters
the queue, it is sent out to the link. If you just gave the voice
traffic a specific amount of bandwidth, there is no telling how long the
rtp packet would be in the queue before transmission, hence jitter. The
downside to rtp priority is that if there is anything other than rtp
that you need give priority (like control traffic) you cannot do it.
You must use some other means. Hope this is what you are looking for.
Thanks

If I am going to make sure that I reserve bandwidth for voice across the
frame....would it be more correct to do this:
map-class frame-relay FR
frame-relay fair-queue
frame-relay voice bandwidth 1000000
or, this.....
map-class frame-relay FR
frame-relay ip rtp priority 16384 16383 1000
