I think this kind of setup will work just fine, but being a newbie, I just wanted to make sure.
Originally, I wanted to eliminate the monthly charge to ATT for my land line by porting my number to tracfone and then to google voice and use the google voice/google chat/obi110 solution documented in this forum. After porting my number to tracfone, I find that google will not port it from tracfone to google voice. So if I go back to ATT but get a cheap, "no long distance" plan, can I configure/connect the obi such that:
1. when I call out can I just dial the number and it will go through google (no long distance charges, no special dialing sequences)
2. when someone calls my long-held home phone number, my home phone will ring just like before
3. 911 will call the local 911 dispatch center
