Hi there,
I've been happily using GV with OBI110 for years now. After a protocol change from Google which made OBI110 incompatible I successfully switched to simonics gvgw service and all worked just fine (although with some intermittent disconnect and audio issues which were come and go on their own) for a year or so.
Recently in June of 2018 I started experiencing two issues with no change on my setup whatsoever:
1. No incoming to me audio after I call a phone number
2. No incoming call at all after I call my GV number form an another phone.
I did some searching and found a OBI110 firmware upgrade which supposed to eliminate a need for simonics protocol translation service from
obifirmware.comI installed it and stopped using simonics. It helped marginally as I still was getting my no incoming audio and no connection to my GV issues, although I got everything working intermittently, but only very few times.
I decided to upgrade to OBI212 and with high level of hopes configured it today to only see couple of new issues. My first issue was "registration not required" issue. At that time when I checked my Google GV account page in settings I noticed that additionally to Legacy Google Chat (checked on) I got a OBIHAI option. I was hopeful that this is very much anticipated "new Google OBIhai interface", however GV service did not work with IBI212 at all.
I then reset to factory settings on my OBI212, deleted my device on OBITALK and started from scratch. At this time I got everything right on OBITALK status with device showing "connected".
I was happy for a minute. A call to my GV number from my cell phone got through and worked fine. I was even happier. However, when I dial a number from my OBI-connected home phone to any other phone I do not have audio coming. - Same issue as before. I tried a few times and got it working once w/o changing anything. So it is intermittent, but mostly not working.
To be honest, I am frustrated... My intent is to return my OBI212 and forget about obihai/polycom altogether.
However, having a Holiday and an easy week ahead I might still try to troubleshoot if I got even a slight idea what I possibly can do.
Any advice (or even experience sharing) would be greatly appreciated.
And yes, I did all the OBI config correctly. As well as my router settings etc.
