I've been trying to fax with my Epson WF-610 MFC which is connected directly to my ATA but have been totally unsuccessful. It's only got 2 options for faxing (Disable V.92 and Disable ECM) which I've disabled to no avail. Baud rate can't be capped and seems to be too high as is.

Has anyone gotten fax working over FTTN and if so what make and model do you have? I think some HP's may be more resilient from reading on the U-Verse forums but Sonic's ATA's may be configured in such a way that introduces problems.

The Grandstream manual for the FTTN ATA shows a number of options for faxing and even making faxes more reliable over VoIP but the GUI is disabled once provisioned so I can't see what the settings are or attempt to change them.

Would really love to get fax working! Any suggestions appreciated.

Have you tried changing the codec to G.711?

There is info about it in a thread about alarms, link below. I tried using this with a modem just to see if it would work and it did not, but there is some chance it will work for your FAX.

I'd recommend using Sonics included fax line service (in the labs area of your account). It lets you send faxes online using a PDF or jpeg attachment. It also gives you a separate incoming fax number and will email you incoming faxes as an attachment. Really handy when you need it.

I appreciate the info mediahound. The main issue is HIPAA compliance which the fax services are not and being able to receive faxes on an existing fax number that was ported to Sonic.

The Grandstream ATA definitely supports it, but the GUI is locked down after registration and I think some default settings in the ATA for fax may have been switched and are affecting faxes (for machines that don't support lowering baud rate [which is a large number of consumer machines from what I've found]).
