2568 CHAPTER 173: VOIP CONFIGURATION COMMANDS
Description Use the default entity compression command to globally configure a default
codec.
Use the
undo default entity compression command to remove the
configuration.
By default, the codec with the first priority is g729r8, that with the second priority
is g711alaw, that with the third priority is g711ulaw, and that with the fourth
priority is g723r53.
The default entity compression command can be used to globally configure the
default mode of the voice coding and decoding. After the configuration, all the
voice entities and newly created voice entities on this router, which have not been
configured with this function, will inherit this configuration.
Related command: compression.
Example # Adopt the g723r53 coding and decoding mode as the first selection globally.
