Nothing seems to work to when entering the info. If you just enter the required info in the obitalk web interface it says unregistered. If you then manually go in and try to enter the info based on random forum suggestions from 2011 you get Register Failed: 403 Forbidden.
There are no instructions on how to get this working with Ringcentral.
Are you looking at http://www.obitalk.com/forum/index.php?topic=827.0 ?
Looking at many different things but yes that is also one of them. I reached out to support and they asked me for my info that was entered into the Obitalk web interface for RingCentral and have not heard back from them.
If they support RingCentral and have a web interface customized for it with no other instructions one would think that there is nothing else to do but fill out the form.
Where did you purchase the OBi 302, and did you really, truly mean "302" and not "202"?
