Leland, Are you sure that you are up to date on the latest developments with QoS on IP? Bellcore specs call for no more than 150usec end-to-end delay, however this can be realistically stretched to 200usec and still not be detectable by the human ear. But you are correct that it is the regular delivery of the packets/cells that is important. This can be done in an IP network much the same way that it is done in voice over frame relay environments; through fixed length frames/packets and priority queuing for the voice packets. Not to say that ATM doesn't have its place, but VoIP is real and deployed. In fact LU has made public statements that the will focus their future efforts on ATM and IP solutions. In the same statement though they said that they would not be pursuing VoFR as a strategic direction (I believe that their OEM agreement with ACT Networks will fill this tactical niche). It would take a few minutes to find the URL for the statement, but I can if you would like. The point being is that LU also agrees that voice over IP is a strategic direction that they must pursue.
