Oh, it was meant for him. In the time it took him to write his wrong 
e-mail he could have gone to the ITU web site, downloaded a free copy of 
the T.38 spec, looked up the annex where it described the negotiation 
process, and found a clear statement of what is supposed to happen. Of 
course, that wouldn't tell him the real world issues, like the fact half 
the T.38 implementations out there don't follow the spec., but it would 
have been a valuable start. It would also keep the noise level on this 
list down.

What a lot of people don't allow for when writing garbage is it stays on 
the internet for years, and eventually becomes reference material. :-\
