Greeting

Greeting is an act of communication in which human beings (as well as other members of the animal kingdom) intentionally make their presence known to each other, to show attention to, and to suggest a type of relationship or social status between individuals or groups of people coming in contact with each other. While greeting customs are highly culture- and situation-specific and may change within a culture depending on social status and relationship, they exist in all known human cultures. Greetings can be expressed both audibly and physically, and often involve a combination of the two. This topic excludes military and ceremonial salutes but includes rituals other than gestures.
Greetings are often, but not always, used just prior to a conversation.
Some epochs and cultures have had very elaborate greeting rituals, e.g., greeting of a king.

telephone greeting

Most languages have alternate greetings to be used over the telephone. In this case, the greeting is meant to confirm whether the person on the other line is present.
The term "greeting" may also refer to a pre-recorded message replayed when the call cannot be answered.
