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.
