asterisk users - Dec 2004 - help with detecting fax.

Hi, 

I am looking at getting adtran tsu 600 p/n 1200.076L2 for my small office

It comes with 6 FXS ports and I would use 2 X100Ps for FXO ports.

Would that work ? Is there anything I would have to be aware of in such
configuration?

What would be a better solution?

robert

I have Spandsp working fine. Asterisk sees a fax on the zap port and redirects
the call to the fax-in area.

This works if I have a simple dialing rules that goes answers first and waits 10
secs then goes to the next item. If it hears a fax it goes to the right place.
Here is a sample that works.

[incoming]

exten => 2019,1,Goto(test,s,1)

[test]

exten => s,1,answer
exten => s,2,wait(5)
exten => s,3,Macro(stdexten,Sip/101)

exten => fax,1,Goto(fax-in,s,1)

[fax-in]

exten => s,1,Dial(zap/1)

But if I use this following macro it just detects the fax then goes to
congestion instead of the fax extenstion.

[macro-followme]
;
; Standard single line follow me then to voicemail
; $ARG1 first device to dial to. $ARG2 2nd device to dial.
;
exten => s,1,Answer
exten => s,2,Wait(5)
exten => s,3,Dial(${ARG1},20)
exten => s,4,Dial(Zap/g1/${ARG2})
exten => s,5,Voicemail(u${MACRO_EXTEN})
exten => s,104,GotoIf($[${DIALSTATUS}=CHANUNAVAIL]?105:107)
exten => s,105,Dial(Zap/g1/${ARG2})
exten => s,106,Voicemail(b${MACRO_EXTEN})
exten => s,107,Voicemail(u${MACRO_EXTEN})
 
exten => fax,1,Goto(fax-in,s,1)
;
I am calling it with this setup.
exten => 2019,1,Macro(followme,Sip/101,16502468900)
Here is the error I get.  And yes I have exten fax,1,Goto(fax-in,s,1) in the
inbound context as well.

"followme|Sip/101|16502468900") in new stack
