Doesn't anyone really remember the whole smart-v.-stupid network analogy? Not meaning to start a flame war here, but trying to stick all of the intelligence back into the network is not exactly a win-win proposal.
Yes, in a perfect world you're correct, but the equipment which does POTS<->VoIP is probably easier (and cheaper) to do if it has a static 40ms jitterbuffer instead of having to constantly adapt. Echo-cancellation probably is easier to do if delay is constant (which it is with constant jitter-buffer). OTOH the echo cancellation should be done in the POTS-VoIP interconnect and the echo is only present in the POTS part so that should work anyway. But then again, that's why Skype is to successful, it adapts to network conditions, so it might be that this way will prove more successful. -- Mikael Abrahamsson email: swmike@swm.pp.se
