Caller ID is the number presented to people you call. It can be set up to be identical to or different from your company's main number or your own DID number, if you have one.
Having alternative caller IDs is useful, for example, for a call center working with more than one product or service. Or you may want to have a specific caller ID for an ad campaign or a new product launch, etc.
To select a caller ID tap 
on the bottom-right corner to access the TeleConsole's settings.
The settings screen is divided into three categories - Channels, General, and Local Settings.
Scroll down to find General and tap Caller ID.
A list of available caller ID numbers will be displayed. This list is created by your administrator. If you require any additional numbers you should request them from him.
Select any number from the list to set it as your caller ID for all your outbound calls and outbound faxes.
Select Default Caller ID if you are not sure what caller ID to select. This will make the caller ID a number set by your administrator as a general Caller ID for your company.
Select Blocked to hide your number completely. Instead of a number the recipient of your call will see a "Blocked", "Not available", or a similar message.
