Changing Codecs
Before voice traffic can be transmitted over a digital network, the audio
waveform, an analog signal, must be encoded into a digital format. The
digitized audio is packetized and delivered over the network to a
destination, and then decoded back into a voice waveform. Software
called a codec (coder/decoder) converts the audio information between
digital and analog formats.
Digitized audio formats have different properties. Each format represents
a compromise between bandwidth and audio quality, that is, high quality
audio typically requires more network bandwidth. Compressing the
digitized audio data can conserve bandwidth with little compromise in
audio quality, but compression requires increased processing overhead
when encoding and decoding the audio information. Too much
processing overhead can introduce delay.
IP Messaging can operate with either the G.711u codec or the G.729a
codec.
Each codec includes a set of language prompts. By default, IP Messaging
operates with the G.711u codec and US English language prompts.
Each set of language prompts, available with the G.711u codec or the
G.729a codec, is constructed as RPM Package Manager package. For
example, IP Messaging provides the following two RPMs for UK English:
■
IPMSG-UK-EN-G711u-SPEAK-1-1.i386.rpm
■
IPMSG-UK-EN-G729a-SPEAK-1-1.i386.rpm
