Can you confirm on the Cisco that you are successfully tagging on the
VoIP traffic?  I think I remember you said there were no QoS errors,
but you can also watch the packets going through the QoS rule (can't
remember command right now, but I'll look it up).

Aha!  How much traffic and what sort is it?  Anywhere near saturation?

Sorry, I don't remember if you mentioned this, but what is your
hardware setup, and how many calls do you have going through the T1
link?  What codecs are you transcoding to/from?
