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.
Codec
Coder/decoder
Codec is a procedure that digitizes and compresses analog voice before it is sent via
the Internet, and decodes – i.e. translates into analog 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 establishing a connection.
The choice of codec is a compromise between voice quality, transmission speed
and the necessary bandwidth. A high level of compression, for example, means that
the bandwidth required for each voice connection is low. However, it also means
that the time needed to compress/decompress the data is greater, which increases
execution time for data in the network and thus impairs voice quality. The time
required increases the delay between the sender speaking and the recipient hear-
ing what has been said.
COLP / COLR
Connected Line Identification Presentation/Restriction
Service characteristic of a VoIP connection for outgoing calls.
COLP displays the phone number accepting the call on the calling party's display
unit.
The number of the party accepting the call is different to the dialed number, e.g. if
the call is forwarded or transferred.
The called party can use COLR (Connected Line Identification Restriction) to pre-
vent the number from appearing on the calling party's display.
Consultation call
You are on a call. With a consultation call, you interrupt the conversation briefly to
establish a second connection to another participant. If you terminate the connec-
tion to this participant immediately, then this was a consultation call. If you switch
between the first and second participant, it is called Toggling.
