as stated in the documentation, it's allowed to set 
FAXOPT(faxdetect)=yes/no to allow fax detection.

It's done (see below) but still fax detection :-( Extension 300 is 
hylafax with iaxmodem.

On the upper Asterisk gw it's the same, despite the faxdetect set to no 
we also have the NOTICE of T.38 re-INVITE. Test is done with a mobile 
phone calling the 0123456789 PSTN number.
