A
Address of Record (AoR)
A SIP URI that represents the "public address" of a SIP user resp. a phone or line.
The format is similar to an E-mail address: "username@hostname".
ADPCM
Adaptive Differential Pulse Code Modulation. A compressed encoding method for
audio signals which are to be transmitted by a low bandwidth. As opposed to
regular PCM, a sample is coded as the difference between its predicted value and
its real value. As this difference is usually smaller than the real, absolute value
itself, a lesser number of bits can be used to encode it.
C
CSTA
Computer Supported Telecommunications Applications. An abstraction layer for
telecommunications applications allowing for the interaction of CTI computer
applications with telephony devices and networks.
CTI
Computer Telephony Integration. This term denotes the interaction of computer
applications with telephony devices and networks.
D
DFT
Digital Feature Telephone. A phone with no line keys.
DHCP
Dynamic Host Configuration Protocol. Allows for the automatic configuration of
network endpoints, like IP Phones and IP Clients.
DiffServ
Differentiated Services. Specifies a layer 3 mechanism for classifying and
managing network traffic and providing quality of service (QoS) guarantees on IP
networks. DiffServ can be used to provide low-latency, guaranteed service for
e. g. voice or video communication.
DLS
The Deployment Service (DLS) is a HiPath management application for the
administration of workpoints, i. e. IP Phones and IP Clients, in both HiPath- and
non-HiPath networks.
