ini File Field Name		Valid Range and Description
Web Parameter Name*
CoderName	CoderName = Coder,ptime (can appear up to 5 times)
[Coders]	The following coder names can be selected:
	g711Alaw64k	– G.711 A-law.
	g711Ulaw64k	– G.711 ∝-law.
	g7231	– G.723.1 6.3 kbps (default).
	g7231r53	– G.723 5.3 kbps.
	g726	– G.726 ADPCM 32 kbps (Payload Type = 2).
	g729	– G.729A.
	NetCoder6_4	– NetCoder 6.4 kbps.
	NetCoder7_2	– NetCoder 7.2 kbps.
	NetCoder8	– NetCoder 8.0 kbps.
	NetCoder8_8	– NetCoder 8.8 kbps.
	Transparent	– Transparent coder.
	Evrc	– EVRC coder.
	Amr	– AMR coder.
	Note: The coder name is case-sensitive.
	The RTP packetization period (ptime, in msec) depends on the selected Coder name,
	and can have the following values:
	g711 family	– 10,20,30,40,50,60,80,100,120 (default=20).
	g729	– 10,20,30,40,50,60,80,100 (default=20).
	g723 family	– 30,60,90,120 (default = 30).
	G.726	– 10, 20, 40, 60, 80, 100, 120 (default=20).
	NetCoder family	– 20, 40, 60, 80, 100, 120 (default=20).
	EVRC	– 20, 40, 60, 80, 100 (default=20).
	AMR	– 20 only.
	Transparent	- 20, 40, 60, 80, 100, 120 (default=20)
	Note 1: If not specified, the ptime gets a default value.
	Note 2: Each coder should appear only once.
	Note 3: The ptime specifies the maximum packetization time the gateway can receive.
	Note 4: G.729B is supported if the coder G.729 is selected and
	‘EnableSilenceCompression’ equals 1 or 2.
	Note 5: The selected rate of the AMR coder is set according to the parameter
	‘AMRSendRate’. The selected rate of the EVRC coder is set according to the
	parameter ‘EVRCRate’.
	Note 6: The AMR coder is enabled only if ‘DSPVersionTemplateNumber = 1’. When
	this DSP template is selected, the maximum number of channels is 160 instead of 240
	(rounded to full E1/T1 trunk capacity 30/24 channels per trunk).
	Note 7: The EVRC coder is enabled only if ‘DSPVersionTemplateNumber = 2’. When
	this DSP template is selected, the maximum number of channels is 120 instead of 240
	(rounded to full E1/T1 trunk capacity 30/24 channels per trunk). Note that the value of
	the parameter ‘EnableRFC2658Interleaving’ must be identical on both sides of the call.
	For example:
	CoderName = g711Alaw64k,20
	CoderName = g711Ulaw64k,40
	CoderName = g7231,90
AMRPayloadType	Determines the payload type that is used when the selected coder is set to one of the
	AMR coder variants.
	The valid range is 0 to 120. The default value is 64.
