Short version:
GV MWI (stutter tone and visual indication) is working fine on an OBI 200 SW 3.0.1 (Build: 4367) configured manually using the OBI 200 web interface and never configured in the OBITALK portal.
Long version:
I just got an OBI 200 that came with SW 3.0.1 (Build: 4367). I was an early adopter of the OBI 110 and after just updating the 110's firmware and getting forced into using the OBITALK gateway and the new Google authorization, I made sure to stay away from OBITALK and disabled firmware updates and OBITALK before letting the OBI 200 have internet access.
(Updated my OBI 110 fw from this thread Build 2872

After manually setting up
voip.ms, 2 GV lines and a free Callcentric DID using only the OBI200 web interface, GV voice mail indication, both stutter tone and visual indication, is working fine. I'll definitely avoid any firmware upgrades and will be one pissed off customer if they manage to force one. They shouldn't be able to unless they've left a hidden backdoor access mechanism.
I've been away from these forums since the first few months after the OBI 100/110 release and was appalled to find OBIHAI no longer allows firmware downgrades. On top of that they don't even seem to be providing release notes for many firmware versions. I can't find any info on the changes to the OBI 110 firmware I upgraded to or the firmware that came on my new OBI200.
As an early adopter of OBIHAI's products, I'm disappointed to see their focus has shifted so much. Even with their new business focus, I don't understand companies who prohibit firmware downgrades and avoid doing business with them whenever possible. No one is perfect and I won't accept downtime when a firmware release breaks something critical to me when a simple downgrade to a previous version could get me back up quickly.
