Thanks for the input. I am getting faxes into asterisk fine, but from other PSTN connected faxes. The problem is being at home (without a Bell line) and trying to fax out to either my asterisk box at 151 front, or another PSTN attached fax machine with a PAP2 over Cogeco cable. The internet connection works very well for voice, basically perfect as far as I can tell, but fax fails 100% of the time, it doesn't even start to communicated.
My PAP2 makes the call and it starts fax tones and then I get a re-order signal. I tried sending to a TDM faxing service that I still control (NMS on PRI) and the message says that the far end (my home fax) hung up, but seemingly that's not the case as I can hear the device still has hold of the line. It's a real fax machine (Samsung CLX-6200FX) not software on windoze.

If you are faxing to the PSTN, you'll need a T38 capable gateway which can be asterisk but requires PSTN card of some kind and the T38 add-on and license from digium. If you have an external device as your PSTN gateway (for example a Cisco router with a PRI card), then you don't need anything on the Asterisk server except allowing T38 pass-through. If you are doing SIP-to-SIP then just two T38 ATAs will work with asterisk in T38 pass-through mode. If you buy service from a VOIP provider, most are now T38 capable so all you need is the T38 capable ATA. (the PAP2 & PAP2T do _NOT_ have T38 despite what you might find in a google search). You can force g711 and all the settings you mentioned and it will sometimes work, but bottom line; you'll never get more than a few pages through at a time if you're lucky.
