Thanks for the details. We can rule out a call forwarding loop.
"Currently 202 has NO GV accounts setup SP1-4 are empty. That, I'm guessing, is what I'm not getting the message, "No service configured error. Please log into
ObiTalk.com & configure your device." when dialing out on 200's SP1."
That's impossible. You wouldn't hear a message on a phone plugged into the 200, which relates to the 202.
Let's start over, and build this up in stages.
Unplug the 200 from power, unplug it from the house wiring, and plug in just one standard telephone, and no fax.
Unplug the 202 from power. Delete the 202 entirely off of your OBiTALK dashboard for now.
Plug the 200 back into power and Ethernet, , and wait for it to reboot. Look at its status on your OBiTALK dashboard. It should show SP1 GV status as "connected", and SP2 status as "registered". Does it? If so, confirm that it properly makes outbound calls, displaying the
correct Google Voice account #1 caller ID to the called party's phone, and you can call it from some other non-Google Voice phone number, and it answers, and you don't hear any error messages. Does that work? If not, stop here and report back.
If that worked, then unplug the 200 from power. Unplug the telephone, and plug it into the Line 1 jack on the 202. Do not plug anything into Line 2, and do not attach a fax machine. Unplug the Ethernet cable. Power up the 202. After it powers up, dial ***8 from the attached telephone, then dial *1 to confirm resetting it to factory defaults. Wait for it to reset and completely reboot. Unplug it from power. Reattach the Ethernet cable. Plug it back into power and let it reboot. Add it back to the OBiTALK dashboard using the **5 procedure. After the addition is complete, then configure one, and only one, of your other two Google Voice accounts on SP1. Do the same inbound and outbound call tests. Confirm that the correct Google Voice account #2 caller ID appears on the called party's phone. Does that work?
