Whois & Analysis for callername.com

Caller ID (caller identification, CID), also called calling line identification (CLID), (CND), calling number identification (CNID) or calling line identification presentation (CLIP), is a telephone service, available in analog and digital phone systems and most voice over Internet Protocol (VoIP) applications, 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.

Caller ID may be used by the recipient to avoid answering unwanted incoming calls by the concept of informed consent.

However, it also poses problems for personal privacy.

Usually, the caller can disable or "block" the Caller ID facility, but some call capture technology can bypass a caller block.

On the other hand, the possibility of caller ID spoofing may render received information unreliable.

A missed call is a telephone call that is deliberately terminated by the caller before being answered by its intended recipient, in order to communicate a pre-agreed message without paying the cost of a call.

For example, a group of friends may agree that two missed calls in succession means "I am running late".

The practice is common in South Asia, the Philippines and Africa.

A telephone number is a sequence of digits assigned to a fixed-line telephone subscriber station connected to a telephone line or to a wireless electronic telephony device, such as a radio telephone or a mobile telephone, or to other devices for data transmission via the public switched telephone network (PSTN) or other private networks.
