Oh if life was as simple as you see it. and IP protocols were all the same.
read up on T38 firstly, Then read the technical build of a 3300 . Yes it
will be coming along soon but at the moment the fax needs to stay on the TDM
side of the e2t bridge.
The rason for T1 is it will give you the 24 channels and also the call will
stay the right side of the e2t rember fax is NOT ip its a stream or 0s and
1s and its also serial so if you loose a bit you are in trouble.
so resampling it to put through codecs causes many problems.
