We purchased the VVX 250 phone to work with Google Voice. We realized we didn't purchase the OBi edition.
After much research and attempts, I was able to convert the phone from UC to OBi v.6.3.1.0,
I am trying to upgrade the firmware and login to the web GUI but the admin/admin password is not working. admin/456 doesnt work either. I am unable to login or update the phone. I tried doing a factory reset from boot and using the <removed by a moderator> as the password for that, and I was able to "Factory Reset" but the default admin/admin password still is not working.
