[asterisk-users] FAX over ISDN PRI

[Mariano Lecuona]

Hi,

All I just want to be able to detect the fax signail while doing an outbout
call taking advance of the out_dialout feature of asterisk. So for to have a
clear image on how i am doing it.

I have my .call that I move the /var/spool/asterisk/ouotgoing like:
(numbers were changed to preserve privacy)

Channel: Local/99999999 at dial_out/n
CallerID: Fax Test <99999999>
MaxRetries: 0
RetryTime: 300
WaitTime: 60
Archive: yes
Context: dial_go
Extension: s
Priority: 1
Set: Q_NAME=511
Set: ANI=99999999

extension.conf

[dial_out]
;
exten => _X.,1,Macro(recordcall,${Q_NAME},${CALLERID(number)})  ;; this is a
custom macro that I created for personal recording puporse
exten => _X.,n,Dial(DAHDI/g1/${EXTEN:0})  ;; this is en sime truck dial
macro that dial into the SPANS -> I know it is OK for sure
exten => _X.,n,Hangup()

[dial_go]
;
exten => s,1,Answer
exten => s,n,Wait(2)
exten => s,n,Goto(${Q_NAME},1)
; If none of above happen, send to queue
exten => _s-.,1,Goto(${Q_NAME},1)
;
exten => fax,1,QueueLog(${Q_NAME}|${UNIQUEID}|NONE|FAXDETECTED|${ANI})
exten => fax,n,Hangup()
;
exten => _512,1,Goto(voicemenu-custom-1,s,1)
;
exten => _5[01]X,1,Queue(${EXTEN}||||${Q_TIMEOUT})
exten => _5[01]X,n,Hangup()
;

chan_dahdi.conf

faxdetect = incoming

I have successfully detected and Answer Machine with AMD application, but as
I experience some dificulties to detect fax I have removed on AMD structure
form the dial plan, only to focus on fax detection. Here is the asterisk
console output when placing a call to fax destination.
