IP Codec Set

The IP Codec Set screen allows you to specify the type of codec used for voice encoding and
companding (compression/decompression). The main difference between codecs is in the
compression algorithm used; some codecs compress the voice data more than others. A
greater degree of compression results in lower bandwidth requirements on the network, but
may also introduce transmission delays and lower voice quality. Codecs are used for VoIP links
between any two VoIP resources or endpoints, e.g., IP telephone to IP telephone, IP telephone
to Media Gateway, Media Gateway to Media Gateway, etc.
The default codec is set for G711MU. The G711MU provides the highest voice quality because
it does the least amount of compression, but it uses the most bandwidth. The G711MU default
setting can be changed to one of two other codecs (and their "flavors") if the G711MU does not
meet your desired voice-quality/bandwidth trade-off specification. For example, if a far-end
server is not running Avaya Communication Manager, you may need to change the codec to
match one that is supported by that server's software.
Usage
Enter the emergency location extension for this
station. Default is blank.
