Caller ID, sometimes called CLI, Calling Line Identity, identifies your phone to the network and is sometimes used by Voipfone to authenticate your call and is essential for some services to work (Mobile Call Back for example).
When this is enabled your number is passed on to the called party who can then see who is calling.
All users have Caller ID enabled as standard and any user with a geographic or non geographic number allocated to their account will show these numbers when they make a call to the PSTN.
Caller ID is free on all active monthly plans and for Voipfone Flex customers, who have calling credit.
There is nothing to do, it just works!
