Tony, the VPM450 is far better than the TE411P's VPM400. One main thing is
that is has full 128ms tails on all spans whereas the VPM400 shared 128ms as
you used more spans, and second is the Octasic chip makes the sound real
crisp and clear.
For the moment, if you need FAX tone detection, you will need to use '
vpmdtmfsupport=0' in your module configuration for loading the
wct4xxpmodule; this will not disable the echo canceler, just stop using it
for tone detection.
Otherwise tone detection should work fine with vpmdtmfsupport=1 ?
