Anveo 911 service account is per OBi unit only and so you must first remove/delete that current Anveo account from your OBi200 first.
Within your OBiTALK account (obitalk.com), select your OBi200 unique 9 numbers 510 XXX XXX. Your Anveo E911 account should be at SP2 so you must remove/delete this first by using the trashcan icon.
When done, to add your OBi202 unit, select Add Device at left of screen and follow steps of adding the OBi202 unit with **5 XXXX and authenticate to your existing Google Voice account first. after SP1 status is "Connected" and you can make all incoming/outgoing calls successfully, go back to your OBiTALK account, select the "Anveo E911 Sign-Up" and be sure to do the Re-Store steps to your existing Anveo Service account.
After SP2 status is "Registered", dial 933 to ensure emergency calls are good and address is good too.
Good luck!
