I can't make any sense out of what you are doing. You proved that Google Voice is working properly. That's how it works. Any behavior to the contrary when using your OBi is a configuration error on your part.
The most basic way it should work would be this:
- You have two different Google/Gmail accounts. Each account has one inbound Google Voice number, and each account may or may not also have one or more mobile or traditional 10-digit land line telephone numbers linked.
- Let's call the two Google Voice accounts "A" and "B".
- You configure account A on SP1, and you configure account B on SP2.
- You point SP1's inbound calls to the PHONE 1 port (the modular phone jack on the back).
- You point SP2's inbound calls to the PHONE 2 port (the second modular phone jack on the back).
- When someone calls A, then the phone line plugged into PHONE 1 will ring; when someone calls B, the phone line plugged into PHONE 2 will ring.
- When someone calls either A or B, and that number doesn't answer, then that caller is sent to the voicemail box of A or B, depending on which of those two numbers they call.
If your setup doesn't do this, and you want it to work as I described it above, then tomorrow, not tonight, delete the 202 off of your OBiTALK dashboard, wait a few minutes, then unplug the 202 from power and from Ethernet. Plug the 202 back into just the power plug and the telephone jack. Wait for it to boot up. Pick up the phone and you should hear a dial tone. Press ***9 then 1 to restore it to factory defaults. Wait plenty of time for the device to restore, reset and reboot. After this is done, then unplug the OBi again, plug in the Ethernet cord and plug the power cord back in, wait for it to boot up, and then follow the **5 procedure to add it back to the OBiTALK portal.
Now, configure only account A on SP1, and set it to ring PHONE 1. Test it. It should correctly ring the telephone plugged into the PHONE 1 jack, and you should be able to answer the call. Test it again, but don't answer. The caller should hear the voicemail greeting you recorded for A. If it doesn't stop here and explain clearly what is happening.
If that worked, then configure account B on SP2, set it to ring PHONE 2, and test calling that number.
This assumes: you have either a two-line analog telephone, or two one-line analog phones. If, and only if, you have a two-line phone, then you must ensure the following: your phone may have a toggle switch on the side or bottom, that controls the operation of its two phone jacks. Use the jack labeled Line 1 + Line 2, or similar wording, and don't use the other jack. Set the toggle switch to use that jack for both lines. Plug a four-conductor/four gold pin phone cord between the L1 + L2 jack on the phone, and the Phone 1 jack on the OBi.
If you have two separate telephones, or you don't have a four-conductor, four-pin modular phone cord, then use two two-conductor phone cords, plugged into the two corresponding phone jacks on the phone and on the OBi. Set the toggle switch on your telephone to use the first jack for line 1 and the second jack for line 2.
