This feature allows incoming calls on your handset to display the virtual number so that you know it's a business call and from which number.
This feature is an additional upgrade which needs to be added to your options. Once it has been added, simply open your call plan and click Divert.
Within the call settings you will see a drop-down option called Display CLI as and here you select the option to be the caller's number.
Don’t forget to SAVE the overall plan once you are finished to active the changes.
