I've been using Obihai devices (110 and 200) with GV successfully, with factory default settings, for around 7 years. My GV is set to forward to both my OBI 200, and my cell phone. I have the latest firmware build 5859EX, and latest GV. My Obi200 is beyond the support warranty.
Sadly, since May 2018 my obi200 device has been unreliable. I have found work arounds which are ok for the short term, but long term are unsatisfactory solutions.
Here are the issues:
1. After powering up my obi and computer in the morning, I get a "Service provider can't access" error message on my phone attached to the OBI200. The rightmost (phone) LED is off or faint. The workaround fix is to do a software reset (not factory default) of the obi200 each day after powering up the device. This must be done daily to restore correct operation.
2. In normal "correct" operation, when I receive a call to my GV number GV will ring my OBI three times. If I don't pick up, the caller is transferred to GV voicemail. Occasionally, however, a GV call will ring my obi200/IP phone only once, instead of the expected three times, then immediately transfer the caller to my cell phone voice mail rather than the expected GV voicemail transfer. Once started, this behavior continues on an ongoing basis. The workaround is to completely remove my obi 200 device, do a factory default reset, remove GV, then reinstall everything as if it is a new OBI200. This solves the problem, at least for a week until it reappears. Then the reinstall process must be repeated.
Both of these problems seem related to software/firmware modifications which occurred in May 2018.
Is anyone else having these issues? Is this an issue with the current firmware? Are there settings different from factory default which might help? My Obi's have always worked with factory defaults; hence I suspect a firmware issue. Polycom will not help unless I update my support contract. My past experiences with Polycom support have not been positive.
Thank you
