I wish I could explain with an image about verifying a phone number.
The site will not accept image uploads like it used to.

You put a number in vPanel => Beta => Mobile

Then that number rings, and you enter the same code displayed on vPanel.
You then have the beginning of a list where you can toggle Auto-Login on and off. (For the remote Access Number.)

In vPanel => Beta => Caller ID

You can select a number from the list to Set Outgoing CID.

Its really that simple
