I don't fully understand your post. Please confirm:
You have one Obi200.
You have 2 GV accounts (ie 2 GV numbers).
Both GV numbers are configured on the OBi200.
You have a cellphone. Is its number registered as a forwarded endpoint with 0, 1 or 2 of the GV accounts?
Using the phone instrument plugged into the OBi200, dial ***1 and note the IP address that is read out to you. Put that address into a browser on the same LAN as the OBi200. At the login page the defaults are both admin.
In the left column click on Status, then on System Status. Scroll down to see the sections for SP1 Service Status through SP4 Service Status. Whichever two of those you used for GV should show Status as Connected.
