SETTINGS
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 KX-HDV800 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.
