[Asterisk-Users] Fax Detection on X100Ps

[Bob Klepfer]

I hate to add to the broken record-like melange of "my fax won't work" 
messages, but everything I've tried with all I could learn from the 
archives has not yet worked to get my fax machine (an HP combo 
tupperware tub) to receive a fax.  In the combo's defense, I can't 
verify that the incoming fax tones are even detected on the * server. 
(is -vvvvc enough v's to see "Fax detected" messages from the zap 
channel?).  The fax extension is never dialed and the incoming fax gets 
dumped to my timeout extension.  Can anyone spot the bonehead move I 
made somewhere?

The setup:
* Server with 2 X100p cards handling our two incoming analog lines. 
  (Gentoo, if it matters---2.4.22-r7 sources)
* SIP only (so far) internally---no FXS cards
* An HP combo fax/copier/printer/dish cleaner connected to a GS
  Handytone 286 ATA
* Incoming and outgoing voice calls are routed fine
* Although I didn't have another machine to fax TO, the HP dials out and
  spews CNG tones
* zap context is "default", "default" context contains fax extension
* on reload, status includes: "-- Added extension 'fax' priority 1 to
  default"
