I have to concede here.  We were able to run the VOIP traffic using UBR, out
not being saturated, this may have helped, on a busy network, a lot of
problems could have
arrisen.  What is nice, is that QOS is easy to enable in ATM.  There are
many reasons that
ATM has not taken off, from a CLEC perspective, I believe it to be the
superior technology.
I would much rather have a 10 Mbps Ethernet feed from a company like Cogent
but those
links do not compare in pricing with DSL.
