My fax no longer completes connection - FIXED!!!!
drgeoff:
If your voice calls are working fine then I very much doubt that fiddling with SIP ALG or X_DiscoverPublicAddress will rectify the fax failures. Those usually address problems of no audio or audio in one direction only.
The usual recommendations for fax over VoIP are to configure the fax machine to lower the baud rate to 9600 and turn off (yes 'off') error correction. If that is successful, try increasing the baud rate in steps until failure reoccurs and then back-off.

drgeoff: Thank you for confirming what I guessed about SIP ALG. I have adjusted the fax baud rate to no avail, it does not affect the issue. (edit: followed your link to voipmechanic... didn't know about "overseas connection". Set it to ON and will see if this helps.) (edit: NO, overseas set to ON does not help)
To all: I do my "fiddling" through the web interface of the device. So far, all I get is screeching. :(
Let me be clear.... the receiving fax answers and they begin handshaking.... the problem is the handshaking stops and disconnects after 3 seconds. My error report says "Busy/No Response" which the book says try again (which is no help). I had the manufacturer (Brother)) tech support try to help, but they claim the problem is with the Voip provider, not the fax. Anveo will not help. I figure it is the settings with either Anveo or Obihai. I need to know whether or not my OBi202 is configured properly. Keep in mind that everything worked for several years until just this last several months. I made no changes to equipment other than dropping ATT DSL for U-verse, which meant a new gateway router/modem.

@LTN1:.... I have the "X_DiscoverPublicAddress" set to the default values. Attempts to change this only result in push back from the OBi202 to restore it to default. IOW, it will not allow anything other than default.

To be clear about my setup: My Brother MFC8660DN line port is connected to the Phone2 port of my OBi202. The Obi202 is connected by Ethernet to my LAN. (Phone1 port goes to an analog desk phone). My Voip account at Anveo has a primary account configured to my Cisco IP phone, and the secondary account configured to my Obi202. The OBi202 is configured for SP1 to be Anveo. No other SPs involved. SP1 is set for line ports 1 and 2. This has not changed, having worked like this for several years.
I do not know if the router/modem gateway swap from 2Wire to Pace caused the problem, or some other upgrade that I am not aware of.
Brother tech support checked my fax settings and found nothing wrong with it. They claim they received my fax, but no other fax machine I have tried will connect long enough to get the document I am attempting to send. I sell insurance products and must have the ability to send applications to various insurance carriers. None of them any longer will connect. This is important to resolve as you can understand.
edit: I tried my other fax (MFC9840CDW) with similar results. The baud rate setting is at Basic (Voip). Same-o, same-o. IOW it is not the fax machine.
In an effort to be thorough, I swapped out the phone cord... no help. Swapped ports on the OBi202... no help.

The screenshot that you attached shows the current configuration page from your LAN--that is, you are viewing that configuration page from your browser via a local access via your local IP address for the device. Are you attempting to make the changes of unchecking from local access also?
From what I've been told (others have more expertise here like Steve), you need to make the changes after logging into your OBiTalk site--under Expert Configuration and then saving the changes from there. If you make the changes locally via the IP address that appears from the screenshot, you will find that when you reboot, the OBiTalk configuration will reload and change what you have made via local access.
When you have confirmed the changes from your OBiTalk web site under Expert Configuration (the link you have to click to enter it on the OBi site), take another screenshot or two of what you did.
