[asterisk-users] Detecting incoming faxes and forwarding to phone fax machine

[Jeremy Winder]

I'm having a problem receiving incoming faxes and I'm hoping someone
here can help me out.

My system is a PBX in a Flash with one dahdi card for my incoming analog
lines and another dahdi card for my analog devices (fax and modem).

My dahdi-channels.conf file looks like:

; Autogenerated by /usr/sbin/dahdi_genconf on Tue Jun 23 14:56:24 2009
; If you edit this file and execute /usr/sbin/dahdi_genconf again,
; your manual changes will be LOST.
; Dahdi Channels Configurations (chan_dahdi.conf)
;
; This is not intended to be a complete chan_dahdi.conf. Rather, it is
intended
; to be #include-d by /etc/chan_dahdi.conf that will include the global
settings

In FreePBX under Inbound Routes I have the following configured:
Fax Extension: 117
Fax Detection Type: Zaptel
Pause After Answer: 5

In FreePBX under General Settings I have the following configured:
Extension for fax machine for receiving faxes: 117

I can call into our IVR and and enter extension 117 and get the fax
machine. So I know the extension is working. However, when someone sends
me a fax I see the following in the logs:

To my untrained eye, I would say this stems from the ZAPTel becoming
DAHDI problem. But I'm clueless how to fix it.

Any help will be greatly appreciated,
