Hi, Gang, I have a small thing I am still clear about, even though I thought it over. what's the difference between VOip over frame Relay and VoFR? Does it mean that for Voip the voice is taken as the data regarded as layer 4 data, then encapsulated in layer 3 ip,then further be encapsulated as layer 2 frame relay frames. but for VoFR, the voice don't need to be encapsulated by layer 3 protocol, and directly passed to layer 2 frame Relay network? could you shed me light over it? I could not turn it over on my brain. Many thanks, ______________________________________
