General explanations

Codecs, bandwidth, delay, jitter and jitter buffer

Codec

Both the IP telephone and IP Office must have an audio Codec. This codes the voice
signals from the microphone for transfer via the transmitting terminal, and decodes the
received audio signals sent to the loudspeaker/receiver of the terminal.

G.711 and G.729 are supported in the IP telephone.

process for audio digitisation

G.729

process

Bandwidth

•

Data flow depends on the Codec and the configured delay.

•

Voice data are not transferred via the packet-oriented TCP/IP protocol on a
continuous basis.

•

The Codec compiles the voice data into a packet during a specific period of
time, 10ms for the IP telephone.

•

IP packets consist of a variable percentage of user data and a fixed
percentage of management information.

•

For small packets the ratio between user and management data is very
unfavourable for the required bandwidth but there is only a short voice delay.
