asterisk users - May 2005 - Fax detection: Problem with extension number

Hello

I've been having the following problem today :
I have a quite simple dialplan made to receive a fax:

[answer-extension]
exten => 1,1,Answer
exten => 1,2,Macro(setcallerid)
exten => 1,3,Ringing
exten => 1,4,Wait(3)
exten => 1,5,Macro(stdfwd3iax-notransfer,${EXTENSION},${EXTENSION},$ 
{EXTENSION})

exten => fax,1,Goto(faxreceive,1,1)

The Wait(3) is there simply to let the system a bit of time to detect  
if it's a fax calling, this has worked so far in all cases except today.
I received a fax from overseas and it seems that Asterisk has been  
unable to detect that it was a fax in the 3 seconds wait. Changing to  
5s was sufficient to receive the fax. But obviously this is not a  
solution I want to adopt all the time as 1-it's a tool long wait, 2- 
what happens if 5s is still not enough another time.

So Asterisk recognized that a fax was being received while executing  
the macro stdfwd3iax-notransfer (this extension simply check

And I saw the following message in the console:
     -- Executing VoiceMail("Zap/10-1", "u200") in new stack
     -- Playing '/data/asterisk/var/spool/asterisk/voicemail/default/ 
200/unavail' (language 'en')
     -- Redirecting Zap/10-1 to fax extension
May 25 01:19:34 WARNING[17629]: pbx.c:2412 ast_pbx_run: Timeout, but  
no rule 't' in context 'answer-extension'
     -- Hungup 'Zap/10-1'

It seems that Asterisk once entered in a Macro is unable to jump to  
the fax extension and gave me a timeout (which I do not handle in my  
dialplan). If I change the Wait(3) into Wait(0) the problem can be  
easily reproduced at all times.

I then added a fax extension in the Macro just in case, but it made  
no difference whatsoever.

Any ideas on what I'm doing wrong or is this a problem with Asterisk?

The fully log is below.
Thank you in advance
Jean-Yves

When I looked in the console on what what happening I say this:

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.
