The best results i had it the multitech modemsdirectly connected to FXS PCI card, you have a nice web interface if you wish also (avantfax) You can find some nice install scripts at the elastix forums.

ADSL, cable etc.... doesn't work properly. FoIP is a lot worse then VoIP. Michael.

Interesting logic. You don't indicate the kind of setup you are using. If you are trying to FAX over a VoIP connection, its probably that connection making FAXes fail. If you are using mISDN, it is probably that making FAXes fail. If you are using zaptel to bring in FAXes from the PSTN, spandsp should work well. If you are using the agx addons to interface spandsp to asterisk, they have just been updated to work with the latest spandsp. This should be more robust in its error recovery than the older versions of spandsp. However, with a good connection to the PSTN you shouldn't be hitting recovery conditions often enough for that to be too serious. Regards, Steve
