To view, add or remove a phone number(s), go to 'Admin' (in the menu) >> click on Phone number under the 'Main functionalities'. You will now see your phone number or a list of your phone numbers and can do one of the following:
Add a phone number. (This is a paid service so please ensure that you are actually adding what you will require)
Edit the routing (how incoming calls are routed) for your selected phone number, by clicking on the icon of the two converging arrows.
Edit the description that you have given the phone number i.e. Main number or Sales number, etc.
Delete a selected phone number(s)
A Dialplan is needed for each phone number so that you can receive inbound calls made to the number.
