OBI200: T.38 faxing - how does it work?

<< < (2/2)

LTN1:
With the OBi200, I don't think it is necessary to turn on ECM. You can also leave it at 14,000 bps instead of 9,600. The OBi really does a great job in the transmission, even with a noisy connection (by that I mean for faxing) like GV.

What I have found when faxing with the OBi200 via a GV connection is that there may be small evidences that not 100% of the contents make it through. It is sort of minor but you may see a streak through one of the lines. When using a standard VoIP line like CallCentric and the OBi200, you will find the transmission near perfect. Overall, the OBi200 will make VoIP faxing reliable, even when using GV.

I'm wondering if you can tell me what make and model Fax machine you used to successfully send and receive faxes using Google Voice?  I am able to send ok but can't seem to receive getting the message "no answer" or just "failed".

thogan:  please don't cross-post the same issue you posted elsewhere.  It makes it too difficult for other users to benefit from the discussion.

First of all, does it work with Google Voice?


Google Voice does not support the T.38 protocol
You'll just be using the G.711u codec when faxing with Google Voice.
