Luck? What did you change, and what happens when somebody tries to send you a fax? The fax machine connects for 5 minutes and then gives up, or what?
Did you try making the fax line only accept T.38? What happened? You can look at Status>Call Status during a call to see what codec is being used. I can't try that because my SIP plan does not support T.38 I don't know if yours does. Maybe yours does not either.

If Freephoneline does not support T.38, it will do no good to try and use it.
Instead, on the OBi only allow G.711u or G.711a. Hopefully Freephoneline supports those! (They date from the Bell system in the 1970's dawn of digital phone equipment.) 'a' is likely better (it sounds better if you have good equipment and ears) but 'u' is the typical north american standard.
On the fax, limit the speed to 9600 (usually, but you might try slower) and turn OFF error correction. (ECC gets confused by VoIP and will terminate the call.)

I've tried a variety of things that I have found on the net that supposedly worked for other equipment combinations on Freephoneline, all without success, don't remember all the details now, and have turned everything back to factory defaults since nothing that I have tried worked.
I am not trying to receive faxes at this point, only send. There is another way to receive them that I will work on later, but now I am concentrating on sending only. Freephoneline does not provide support for faxing, but I have read that it can be done with their system, they just won't help if there is a problem. I have not seen any information on how to do it with an OBi 202, so I think I am in uncharted territory.
Unfortunately I am only hacking as I don't have a PhD in faxology, lol.
When I tried faxing, I got the ring, the handshake, and it looked like it was going to work. Then it hesitated for a while (maybe a minute) and then gave me a communication error, don't remember the number, but always the same error.
I will try the suggestions from Shale and sdb- and report back, thanks for the suggestions.

After almost giving up on using this set up for sending faxes, my last attempt provided a positive result, so for anyone with similar equipment and service provider here is how I did it:
OBi202 configuration - Codec Profile B - all codecs disabled with only G711U left on.
Brother MFC-490CW settings - Menu>Fax>Miscellaneous>Compatibility>Basic(for VoIP)
A word of caution - I don't know if it was a fluke that it worked, as I have only send a single page for which I got a "completed" message on the fax machine. I don't know if will work again or if it will work for multiple pages. I have not contacted the recipient to ensure that the fax got through OK. Hopefully all is good for all faxes, though.
Thanks, sdb-, for your suggestions.
