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.
