Chatting
Form of communication on the Internet. During a chat, brief messages are exchanged
between the communicating parties in real time. Chatting in this sense is understood to
be a written form of communication.
Client
Application that requests a service from a server.
CLIP
Calling Line Identification Presentation
Telephony feature. The number of the caller is transferred to the called party's phone dis-
play (if the caller activates this feature). The called party's phone must be compatible with
CLIP and the feature must be enabled on the phone port.
Codec
Coder/decoder
Codec is a procedure that digitalises and compresses analogue voice before it is sent via
the Internet, and decodes – i.e., translates into analogue voice – digital data when voice
packets are received. There are different codecs, with differing degrees of compression, for
instance.
Both parties involved in the telephone connection (caller/sender and recipient) must use
the same codec. This is negotiated between the sender and the recipient when establish-
ing a connection.
