1. Yes, all devices in the same account have the same level of access to each other.
2. Each device is assigned a speed location in the other devices by Obihai. Depends on which device you
are calling from as to what speed dial number you need to dial to reach the specific device.
Just dial the single digit for the assigned location and wait 2 seconds, the call will be placed.
3. Once Obitalk adds the devices to the circle of trust the default will be for all incoming calls from
those devices to be sent to the AA.
4. Should work ok. You may have a reason for forwarding your home number to GV, such as using
google's voice mail. You can have your home Obi forward, or fork, the calls to your remote Obi without
going through GV.
5. Should work ok. If you only have the line connected (or have not changed the default line for outgoing calls) all calls placed through the AA will use the Line port.
