I realize this is an old problem, but I'm stumped here, as all the steps I've seen so far here have failed me.
I have a Obi202 device that was working fine. I needed more ports, so I picked up a Obi504 which I thought would work, but it appears that device refuses to operate with Google Voice. I'm not sure why, but it never showed up in devices and did nothing (Callcentric number works fine with this unit, however...)
I decided to re-install my Obi202 device. I:
Removed all devices from my ObiTalk account.
Reset the device to factory via the local web admin settings.
Deleted all mention of devices and accounts in my GV accounts.
Re-added the device via the dashboard.
Re-added my first GV account, which is the admin account for the device. It configured fine.
Added my second GV account, it configured fine.
Added a Callcentric account, it registered ok.
Verified that the GV accounts are forwarding to the Obi device on the web (and a sip number is shown in legacy settings.)
Waited a while then rebooted everything with a hard power pull.
Dialed *79 to disable DND
Checked that **9 222 222 222 was properly giving echo.
I can make outgoing calls without issue. Incoming calls simply go to Google's voicemail. I do not see these in the call history of the device, but outgoing calls do appear here. The Callcentric number receives calls without issue (it cannot dial out, it's an old freebie number.)
Everything I've found in the forum says, more or less, just wipe everything and start over. I've done this a few times, but have no incoming calls. I'm obviously missing something - what is it?
