The bottom post in this thread gives the gizmo tweaks that for some make faxing more reliable. I have had no issues with my older HP Laserjet 3150 All-In-One but I implemented the exact same tweak on a Brother Intellifax that was more or less "hit or miss" and it works well now. Try the gizmo tweaks and, if you could, let us know here how you fared with it. Keep in mind this works only if you have expanded access to the gizmo, not the "Welcome" screen.

I'll just quote the appropriate section here so others (who kept expanded gizmo access) interested in tweaking for their faxes may benefit:
_____________________________________________________________
The settings that I saw(before the password change) that were modified by SR upper level tech support that made faxing work were:
Sip tab:
Uncheck T38 fax support
Codecs tab:
Turn silent suppression on for all codecs
Use fixed jitter buffer at 80 ms
On your fax machine:
Disable error correction mode(SR actually told me to turn on error correction and it did work. I turned it off to test if it would work without error correction. It did and was much faster without the error correction)
Reboot gizmo after changes!
This is what was done to correct my faxing issues....each fax and SR line is an individual and the results may vary.
My setup:
Linksys cable modem w/Charter HSI(3/256)>Gizmo>Router
Gizmo Line 1 to HP 7210xi all in one fax machine line in
Fax machine Line out to Panasonic 2.4 Ghz wireless expandable phone system w/8 stations
Fax number is set to double ring and fax machine is setup to answer double rings on the first ring.

The posters "erikw2" and "mph300" had SR customer service perform these tweaks for them, but since mph300 noted and reported the changes you could go in there and make the changes yourself to avoid waiting. From previous posts, however, I understand that erikw2 simply called CS (Level 1) and someone performed the fax tweaks for him right on the spot without the need to open a ticket for upper level techs, so if you are uncomfortable making changes to your gizmo setup you may want to try that route.
