Err, if you start your extension definition with answer, then if it
detects a fax signal it will try to redirect to the extension fax.

With my limited testing, it seemed to work quite well. (not tried it
since moving to asterisk 1.4).

It is only neccesary if you want to detect faxes on VoIP communications
(without T.38).

If you want your machine to accept faxes via this method, it may be more
appropriate to use a SIP supplier that supports T.38 and look at using
callweaver instead of asterisk. (asterisk branch that supports T.38 fax
termination).

thanks for your response
Infortunatly the site http://www.newmantelecom.com/asterisk/faxdetect/ is
unrechable for me , so i cant downlood the app and make my test

But i m not sure you understand what i want to realy do

i m developping a  predetive call application for a call center
i make the outgoing call with originate commande (API manager) :

Action: Originate
Channel: SIP/provider/0123456789
Context: foo
Exten: 8000
CallerID: bla
Variable: 0123456789
Async: true
ActionID: xxx
Priority: 1

When the called party pickup the line it redirect to the exten 8000

exten => 8000,1,AMD
exten => 8000,2,Wait(1)
exten => 8000,3,Answer()
exten => 8000,4,GotoIf($["${AMDSTATUS}" ="MACHINE"]?6)
exten => 8000,5,Queue(${var1}|tT|||120)
exten => 8000,6,System(php -q machine.php ${var1})
exten => 8000,7,Hangup

So if the number "0123456789" is ansering machine then marke it and
hungup
if it is a human than redirect to the queue and the agent take the call

did the nvfaxdetect do the same thing like AMD application ?

i dont want recive a fax i want to know i the number a call is not a fax
line because my agents will become Deaf persons with the
zzzzzzzzzzzzzzzzzzzz sound of fax :).

Thanks for your help
