OBi 202 / Freephoneline Faxing
fjl332:
I set up an OBi 202 some time ago and it has been working well for voice calls, but so far I have not been able to set it up to send faxes from my Brother MFC-490CW print/fax/scan/copy machine. The Brother machine is set for VoIP transmissions.
I have the OBi 202 behind a Linksys WRT54GS NAT router. Initially I had the OBi 202 set up also as a NAT router (default) and voice calls worked just as well. Today I changed it to a repeater to avoid having two NAT routers and to be able to access its settings wirelessly with the new IP address issued by the Linksys router, but still faxes don't work. I went into the OBi 202's settings and enabled faxing (which was disabled by default). Still faxes don't work!
I used the OBi Portal to set up my providers, the first being Google Voice and the second Freephoneline to receive calls (since GV does not work to receive calls in Canada). Port 1 is GV and Port 2 is Freephoneline with faxing enabled.
Any help to get my fax service working would be greatly appreciated. Thanks.

So you set Menu>Compatibility>Miscellaneous>Basic in your Fax Machine. I see that there is an Overseas Mode which must be enabled each time you want to try it.
What did "Port 1 is GV and Port 2 is Freephoneline with faxing enabled." mean? Does that mean that you set up the Freephoneonline SP with T.38 enabled and as the preferred codec? If you do that, Freephoneline should do better at faxing. I have not tried it.
You could also see if gain levels help. Here is what I did with my gain levels for voice on my OBi202: http://www.obitalk.com/forum/index.php?topic=5235.0

Thanks Shale.
Yes, I've got the Menu>Fax>Miscellaneous>Compatibility>Basic(VoIP) selected on the fax machine.
Don't know where the overseas mode is.
I am using physical RJ11 port 1 (SP1) on the OBi202 for Google Voice and physical RJ11 port 2 (SP2) for Freephoneline (i.e. where the fax machine is plugged in). I have enabled the T38 codec for SP2, but don't know what you mean by having it as the preferred codec, don't see that option anywhere!
I am using a set of Uniden cordless phones with the OBi202 and found that these phones were actually very loud by default when I started using the OBi202, so I just turned down the volume on the phone sets. Not sure what that has to do with the fax function, though.
My faxing is still not working.

Just noticed that in the in the OBi Setup under
Service Providers>ITSP Profile B>SIP>X_FaxPassThroughSignal
there are options when the default check mark is unchecked, I just don't know if that will help or which option to choose.
Shale:
There are 2 codec profiles, A and B. Make the SIP for your fax VOIP provider be the only one using codec profile B. How? I don't know, but somebody will.
Then disable each codec except T.38 (which seems to be called " fax event" in OBitalk.
Just a general concept. In the admin guide, try searching for "codec profile" to see if that leads you somewhere useful. I know I am being sketchy.
