[Asterisk-Users] Asterisk Faxing

First, please no HTML email.  Not only does it more than double the size of 
your messages, it is plain bad etiquette for mailing lists.

Second, do not reply to a post, erase everything and then type your message 
-- it breaks threading in a horrible way and buries your question in the 
middle of another thread, where fewer people can see it.  Just click on the 
"asterisk-users at lists.digium.com" and start a new message.  It's faster, 
easier and works far better.

I am going to be testing the fax -> TDM400P solution shortly to see how it 
works.  Please keep in mind that if you are connecting a fax machine and 
you expect it to work, you *MUST* use the ulaw or alaw codecs (everything 
else is geared for voice and will horribly break faxes or even DTMF tones) 
and more importantly, you must disable the agressive echo cancellation in 
the zaptel driver, as it tends to kill the faxes own echo cancellation.

Whether you can simply say "echocancel=no" for the appropriate Zap channels 
I'm not sure.

Andrew
