Parameter 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 (namely, 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.711μ-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.
g729r8: G.729 (the voice compression technology using conjugate
algebraic-code-excited linear-prediction), requiring a bandwidth of 8 kbps.
