3.10.4.2.4. Usage Guidelines
Use this command to define a specific voice coder rate of speech and payload size for a dial
peer.
A specific codec type can be configured on the dial peer as long as it is supported by the setting
used with the codec complexity voice-card configuration command. The codec complexity
command is voice-card specific and platform specific. The codec complexity voice-card
configuration command is set to either high or medium. If the codec complexity command is
set to high, the following keywords are available: g711alaw, g711ulaw.
The codec dial peer configuration command is particularly useful when you must change to a
small-bandwidth codec. Large-bandwidth codec, such as G.711, do not fit in a small-bandwidth
link. However, the g711alaw and g711ulaw codec provide higher quality voice transmission
