[asterisk-users] Problem with detecting fax on PRI/DAHDI channels
Hello all,
I am using call files to dial out to a set of PSTN numbers. The calls
are going out fine and being handled correctly by the dial plan.
The problem occurs when I accidentally call a fax machine. I would
expect the dial plan to pick this up and jump to the "fax" extension
in the current context. This is not happening.
In the call file I send the call out via Dial(DAHDI/g0/XXXXXXXX) and
then it goes to my dial plan context:
[SendCall]
exten => start,1,Answer()
same => n, Wait(5)
same => n, ..... ;; do some more stuff
exten => fax,1,Verbose(got a Fax on ${EXTEN})
same =>n, Hangup()
;;;;
I do get a message on the CLI telling me "Channel 63 detected a CED
tone from the network" but still no jumping to the fax extension.
This is while dialplan is in the Wait(5).
CLI> core show version
Asterisk 1.8.4.1-1digium1~natty built by pbuilder @ nighthawk on a
x86_64 running Linux on 2011-05-23 22:05:17 UTC
ISDN lines connected via Digium TE412P card.
I have "faxdetect = both" in chan_dahdi.conf in the general section as
well as specifically for the configured spans.
Would appreciate any help.
Thanks
Sawan

It listens for the CNG tone generated by a (non-V.34) calling FAX terminal. If you are wanting to detect that a number you have dialed is being answered by a FAX machine, there are applications available (but not included with Asterisk) to do that. I believe NVFaxDetect can do it, and most of the add-on answering machine detection applications can do it as well. -- Kevin P.

Same problem, you have these settings AFTER the channel => line, not before.
