problems recieving faxes on asterisk

[Gambit]

I'm having a serious problem receiving faxes on my asterisk pabx. I compiled and installed asterisk on a kubuntu box. I also compiled and installed Asterisk Management Portal (this included compiling and installing spandsp for faxing) and everything seems to work perfectly except for receiving faxes. When a fax call comes in asterisk detects that it's a fax call so instead of playing the digital receptionist voice that i have setup it makes a couple of fax beeps for about a second and then just goes dead. Has anyone encountered an issue like this and solved it?

spandsp still not mature and speed is very slow (9600 max). I'm using Hylafax with AAH + ISDN, works perfectly
