@ STEWART:
Possibly, this is a NAT timeout issue. Test by making a call from the OBi, hanging up, then calling the GV number immediately (within 30 seconds).
I did as suggested, I can place outgoing calls however when I called my GV number, I heard a ring but OBI110 did not ring.
@QBZappy:
I used the dashboard to manage the GV account. No changes, it does not ring on incoming calls.
Any other suggestions?
