Parameters

1st-level: Specifies a codec with the first priority.

2nd-level: Specifies a codec with the second priority.

3rd-level: Specifies a codec with the third priority.

4th-level: Specifies a codec with the fourth priority (that is, the lowest priority).

g711alaw: G.711 A-law codec (defining the pulse code modulation technology), requiring a bandwidth

of 64 kbps, usually adopted in Europe.

g711ulaw: G.711-law codec, requiring a bandwidth of 64 kbps, usually adopted in North America and

Japan.

g723r53: G.723.1 Annex A codec, requiring a bandwidth of 5.3 kbps.

g723r63: G.723.1 Annex A codec, requiring a bandwidth of 6.3 kbps.

g726r16: G.726 Annex A codec. It uses the adaptive differential pulse code modulation (ADPCM)

technology, requiring a bandwidth of 16 kbps.

g726r24: G.726 Annex A codec. It uses ADPCM, requiring a bandwidth of 24 kbps.

g726r32: G.726 Annex A codec. It uses ADPCM, requiring a bandwidth of 32 kbps.

g726r40: G.726 Annex A codec. It uses ADPCM, requiring a bandwidth of 40 kbps.

g729a: G.729 Annex A codec (a simplified version of G.729), requiring a bandwidth of 8 kbps.

g729br8: G.729 Annex B codec. It uses CS-ACELP, requiring a bandwidth of 8 kbps.

g729r8: G.729 (the voice compression technology using conjugate algebraic-code-excited

linear-prediction), requiring a bandwidth of 8 kbps.

Usage guidelines

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.

Examples

# Adopt the g723r53 coding and decoding mode as the first selection globally.
