hello and thank you so much for your reply
just one question: how do you use it? AFAIK, when asterisk receive a call,
it select extensions based on the received number and when it detects fax,
jump to the fax extension. now when should i use these show commands to
detect fax and how should i tell asterisk to execute fax extension?
this is a big problem for me, so i really appreciate if you help me to
solve it.
yours,
SAM
