[Asterisk-Users] Fax detection: Problem with extension number

Wed May 25 23:31:16 MST 2005

For what I'm seeing in your log, the fax is detected, but you're missing
the fax extension. Here is how it works on my asterisk:

zapata.conf:
faxdetect = incoming

extensions.conf:

[pstn-in]
exten => 1234567,1,Goto(fax,s,1)   ; This is a dedicated fax number
exten => fax,1,Goto(fax,s,1)           ; For Zaptel fax detection (must
be answer first to be detected)

[fax]
exten => s,1,ZapEC(off)
exten => s,2,Wait(2)
exten => s,3,RxFAX(/var/lib/asterisk/fax/${UNIQUEID}.tif)
exten => s,4,Hangup
exten => fax,1,ZapEC(off)
exten => fax,2,RxFAX(/var/lib/asterisk/fax/${UNIQUEID}.tif)
exten => fax,3,Hangup
exten => h,1,System(/usr/bin/fax2pdf
/var/lib/asterisk/fax/${UNIQUEID}.tif /var/lib/asterisk/fax/${UNIQUEID}.pdf)

I'm not really sure what exten number to use in fax context, but it works.
