Today, you have a way today to use the Google Talk client with your OBi device configured with Google Voice. This requires that you have separate Google accounts for your OBi device and Google Talk client running on the Windows or MAC pc.
To Make Calls to the OBi (Ring the Phone or Make a New Call):
1. Add the Google Account name for your Google Talk on the pc to your Trusted Callers list in OBiTALK.
2. Add the Google Account name for your Google Talk on the pc as a Google Talk Buddy to the Google Account that you are using on the OBi device.
3. To call the OBi from the pc, just make a Google Talk call to your "Buddy" associated with the OBi device.
4. Since the Google Talk account name being used to call from the pc is in the Trusted Callers list of the OBi, the OBi Attendant will answer and offer the pc user the option to ring the phone connected to the OBi (Option 1) or make new call (Option 2). Use the keyboard on the pc to type 1 or 2 and press Enter. If you are making a New Call, be sure to type the ten digit number followed by the "#" sign (Shift+3) and Enter.
To call the MAC from the OBi:
1. Configure a Speed Dial number for the Google Account name for the Google Talk client running on the pc.
2. Pick up the phone attached to the OBi and dial the speed dial number to ring the Google Talk client on the pc.
