Voice over IP (VoIP)

Fundamentals

101

A modern Intranet normally offers enough performance reserves and reliability to
make good-quality VoIP telephony possible. Specific components can also be
optimised; for example by using a modern switch which evaluates the TOS byte of
IP packets or by replacing unreliable connections.

9.1.2 Latency and Packet Length

For technical reasons, there is always a delay (“latency”) between the recording of
voice data via the microphone and playback via the receiver. Voice data is
recorded for a short period so that it can be sent in an IP packet. The IP packet also
has a signal-propagation delay before the receiver can begin playback. For these
reasons, the extra time required for voice-data encoding and decoding may be
neglected.

An IP packet consists of protocol data and user data. Sending shorter voice-data
packets causes the ratio between the user data and the protocol data to become
unfavourable and increases the bandwidth required. Sending longer voice-data
packets increases latency.

The length of the voice-data packets must therefore be adjusted to the require-
ments of the transmission medium. Shorter voice-data packets can be sent if a
direct ethernet connection exists. If an 64 kilobit/s ISDN line is to be used for trans-
mission, then longer voice-data packets should be used.

Longer voice data packages are generally used for SIP telephony over the Internet.

The following table provides an overview of the required bandwidth for a tele-
phone connection with various parameter settings. The values apply to half-
duplex ethernet; for full-duplex the values can be halved.
