Hello,
Based on your reply it might mean that VOIP overrides Vofr and VoATM ?
I just need to confirm this or otherwise define when Vofr or VoATM would be
needed.
Thanks,
Yasser

If you're configuring VOIP, then you don't need to be concerned about Vofr
or voATM. The voice traffic flows based on the IP network and doesn't care
what the layer 2 link technology is.
You still need to configure QoS, but mostly at the L3 level by prioritizing
precedence 5 packets or their dscp equivalent. How this is done will vary
depending on the layer 2 technology.
HTH a little.

> I need some clarification. When configuring VOIP, but traveling over a
ATM or FR medium, do you still have to address the issues with the L2
technology. IF so what are the key issues for ATM and FR to keep in mind.
For example, with ATM do you still have to configure the vbr-rt and COS. Do
you have to ahve address the fragmenting of data. If a question/requirement
does not speak of this stuff do you still need to configure it. What is the
rule of thumb, when the call works and all is pingable but this L2 feature
and issues are not addressed.
