I have a Obi202 and 2 google voice accounts but just one cell phone. I want to use my primary google voice accounts for my day to day inbound and outbound calls and the other google voice account for ONLY incoming voice mails and incoming text messages. Is this possible tying both google voice accounts to the same cell number.
No, a mobile telephone number can only be used as a forwarding number on one Google Voice account. This is so that Google Voice can route inbound and outbound text messages between the GV number and the mobile number.
If you don't care about using text messages on the GV accounts, you can change the phone type parameter from "mobile" to "work" or "home" on both GV accounts. A landline phone number can be used on a maximum of two GV accounts.
