When you use *72Cell_number you will still get charged twice. The call will be forwarded to your cell via your service provider on SP1.
There are 2 ways not to get charged twice.
1. OBion App
Make sure you are connected after you sign in to OBion.
You will see "Ready" in the upper right of the OBion dial pad
Create a speed dial like: pp(290xxxxxx)
Change 290xxxxxx to your OBion OBi number
Dial the speed dial number
Does the OBion app ring?
If it doesn't, check the call history on your OBi
To access Call History:
Log directly into the OBi using the local interface.
Key the IP address of the OBi into a Web Browser.
Hit Enter
The UserID and default Password are both "admin".
Click Status on the left column.
Then click Call History.
What does it show?
