1. Log in to
www.obitalk.com Here, you will see the OBi Dashboard. Your OBi110 will be listed here as well as your Soft Phone, e.g. the "290" number.
2. Select your Soft Phone. This will take you to the Soft Phone Configuration page.
3. Assuming you have added your OBi110 to your OBiTALK dashboard, you will be able to select it as your "OBi Voice Gateway." Select your OBi110 and submit / save the change. Your OBi110 will reboot automatically.
4. Now, sign-in to OBiTALK with your OBiON for Android app. If you were previously signed in, you will need to sign-out and sign-in again.
You should now be able to dial a number on the key pad of the OBiON app and it will route via GV on your OBi110 to the PSTN.
