There are two facts you need to bear in mind when doing T.38 in 1.4
1) Asterisk 1.4 won't "transcode" between T.38 and ulaw/Alaw
2) The two call legs negotiate codecs independently

So what happens is that a call comes in from a T.38-capable device,
and Asterisk negotiates T.38. The Dial ends up going to a
non-T.38-capable device, but Asterisk won't transcode, so it sends out
T.38 anyway.

This problem makes T.38-support in Asterisk 1.4 fairly useless IMHO,
but maybe you can find a workaround. Luckily it works brilliantly in
1.6.
