Thank you for confirming that there are some bugs remaining. Please continue to report them on this forum and the Google Voice support forum.
If they see enough reports, perhaps they will take them seriously. So far mine has been blown off by "Bluescat" as nonsense! Why would I make this up? I don't need the trouble. Professionally I deal with software bugs as part of my job. We always try to reproduce the problem scenario in the lab, but if we can't, then we collect logs and traces, because sometimes stuff happens in the field that we thought was "impossible"...
I installed and configured my OBI202 shortly after receiving from Amazon on July 11.
It worked fine up until a few days ago, with GV-APP-WIFI and GV-OBI calling as the SP2 service
Then I started losing incoming calls... I'd hear a couple of short rings from the OBI and the caller would get the "disconnected" message.
Usually I could capture the caller-id and call the person back and assure them that my number wasn't disconnected.
I tested it myself from another phone and sure enough the problem existed and was real.
I spent a long time trying to eliminate it, but what finally worked for me was giving up
GV-OBI ... But not just eliminating it from the OBI side, but going into Google Voice "legacy"
and deleting the OBI/SIP definition. Unchecking the fowarding ticky-box was not enough!
OTOH - my wife's GV number is still configured as the OBI202 SP1 service. Outbound from OBI works fine.
Inbound we have unchecked the forwarding to OBI box in GV and use forwarding to a Callcentric account. That is because we get
better CallerId with CallerName service and I've been using that for "free" for years before we upgraded to OBI202.
