Let your friends see that you call them by using the voipGATE CallerID service.
CallerID is a service that transmits a caller's number to the called party's telephone equipment during the ringing signal, or when the call is being set up but before the call is answered. The caller ID can also provide a name associated with the calling telephone number. The information made available to the called party may be made visible on a telephone's own display or on a separate attached device.
Premium call rate users are able to choose if their caller id number is displayed or not when calling someone.
This means you are able to manage your privacy.
