Re: flexfax: problem sending faxes to pxb

[Julio C Spinelli <spine001@gold.tc.umn.edu>]

To have the modem emit this tone, you need to have autoanswer off, 
something like AT+FAA=0 works in many modems. To have this be part of 
the hylafax initialization, you need to add a statement similar 
(please check the manual pages for setup for the exact spelling) to

AdaptiveAnswer: AT+FAA=0 #turns adaptive answer off

To your config.xxx file (xxx represents the device name where the 
modem is) in the /var/spool/fax/etc directory.

Do this and it will work in many home pbxs. There are still some, 
that for reasons unknown to me confuse the modem into getting a busy 
tone and it just hangs up when they answer. Does anybody have any 
solutions for this?

Good luck
