Best fax modem settings to receive from multifunction devices?

I have checked out many posts regarding issues receiving faxes from people using multifunction devices as the sending fax machine. There was a microsoft person who has repeatedly recommended to use a 3Com Courier V. Everything external modem as a replacement for the receiving modem in these cases, inspite of the fact that it is not on the HCL for Server 2003 or SBS 2003. She has mentioned the below devices that are having issues sending fax:

Brother Intellifax 1270E
Brother MFC 8500
HP 6110
HP 7110
Panasonic KXFHD351

I am using a 3Com Courier V. Everything external modem on my server and a clients server. My 3Com courier v and everything external modem is a model 002806-00 while the clients is a model 3CP3453 which is little newer than mine. The box in which each of the modems came said 3Com on it, but both modems say US Robotics on the actual modem. Nor me or him can receive a fax from the Brother MFC830. Below is the error that I am getting in the fax log:

"Reception error" "The remote fax machine did not respond in time, and the call was terminated" "0x40000802" 12/18/2006 10:41:08 12/18/2006 10:42:02

Can anyone please help? Thanks.

I dont think Com port speed is going to change anything, its a problem between the fax modem and the fax machine, and Com has nothing to do with that. You can try to reset the modem to factory defaults, and then look up the ATZ command or something like AT&F. If this fails, then get to the latest firmware for the modem and if that fails again, then your best bet would be to go with another fax modem.

I am going to take a newer USR V.Everything (3453B) out there in the next couple of days. The 3CP3453 already had the latest firmware. I tried the Microsoft "Standard Modem" and "Standard 56000bps Modem" drivers, and the modem would not even answer a call manually, much less on auto-answer!

I have had MultiTech modems in the past, but they had so much trouble receiving from some USR Sportster modems and some multi-function fax machines that I gave up and went with the 3Com Courier V.Everything per Crina Li's and others' suggestions. Except for this one client trying to receive from a Brother MFC 8300, they have worked well.

I was hoping that someone knew an init string that might help with receiving from the Brother MFC device.

What init strings are you using for the mt2634zba-usb with gfi, I have issue when sending because the handshaking is failing at the end of the call.

I cant say what could be the optimal for GFI Fax, but here are the generic strings. I would recommend to ensure its not set any higher than 19200 since anything higher, faxed may fail or the handshake may not occur. I would also suggest contacting the GFI support first to find out whats best for their product.
