OBI202 and Faxing
Lavarock7:
I have 2 Obi202's (setting one up for a non-profit org). I found that one Faxes and the other doesn't. I'm sill testing but here is what I have found. I sent a 5 page Fax to CallCentric using GoogleVoice.
The Obi202 that works is connected directly to my cable modem.
The Obi that doesn't fax (keeps giving communications errors) is connected to a router which connects to the Obi202 that works and then to the modem. I looked at the SIP and SP items and also at the QOS pages. The only difference is that on the Obi that works I also have enabled (rather than default) the Firewall and DRDOSAttackProtection.
Until I can do further testing, I wonder if moving the Obi I'm setting up to be connected directly to the modem might solve my problem.
I'll report back if I find the definitive answer as to whether the Obi placement makes a difference in the ability to Fax more consistently.
Shale:
I presume that voice calls are successful from that phone port that is unable to successfully fax.
I would first move the fax machine that works to the other OBi202. That test would more likely explain the difference as my initial guess.
Still, I think your idea makes sense to try. If the QOS of the OBi router hooked to the modem is causing less jitter, then that would make sense that it would help faxing. So if your computers that are consuming bandwidth during the fax try are holding up the fax traffic, that could explain what you are seeing. We look forward to the results of your test. A successful outcome from your test would probably get a lot of others to try the OBi as router doing QOS.
Lavarock7:
I swapped the test Obi with the working Obi and still could not connect (I may have some other config different, who knows). By the way, voice calls work fine on both units. I am using different GV accounts for the calls, and the software revs are the same, so the next 2 tests are:
1) Configure the test Obi to use the same GV account. If it starts working, then it means that the exchange the GV number is on adds to the problem.
2) Copy then load the working Obi config into the test Obi and use it as the first device after the modem. If this works, then it is probably an Obi configuration issue.
I have had the "production" Obi working for quite a while as the 1st device because I often have downloads going or other heavy usage when talking to my "geek" friend who would be the first to comment on bad audio :-)
If these tests do not confirm why one Obi seems to fax OK and the other doesn't, the non-profit I am testing this for will get my "certified pre-owned" unit and I'll continue playing to find a way to get my own fax system working with the ornery Obi.
Shale:
So the problem follows the OBi.
I would export backups from both units. I would then use a diff (difference) type program to look for differences. For plain text, WinMerge is my favorite such program.
The backups from the OBi local web page are in XML. However I just tried WinMerge on two backup files, and the results look useful.
WinMerge will show differences with a yellow background, at least as I have it set up. While the program will allow you to copy or move snippets from one file to the other (hence "merge"), it works very well to simply show differences.

thanks Shale... never heard of winmerge...
