Media - Alcatel-Lucent OmniTouch 4135 IP Installation And Administration

MEDIA

Select Settings > Media.
The media settings determine how audio is sent between the devices. The devices
negotiate via SIP before a call is connected. All devices must support the same media
types, codecs and security settings.
Codec
Codecs are used to convert an analogue voice signal to a digitally encoded version and
vice versa. Codecs vary in the sound quality they deliver and the bandwidth required.
The OmniTouch 4135 IP supports the most common codecs and each codec can
be given a precedence depending on your requirements for high quality audio or low
bandwidth use.
The priority can be set to from 4 (high) to 1 (low) or 0 (disabled)
G722 G.722 is an ITU-T standard codec that provides 7 kHz wideband
audio at a data rate within 64 kbit/s. It offers greately improved
speech quality compared with older narrowband codecs such as
G.711, but requires a high quality network connection between
the devices.
