Profile Parameters
CoderName_ID
[Coder Group Settings]
112
Coder list for Profiles (up to five coders in each group).
The CoderName_ID parameter (ID from 1 to 4) provides groups of coders that
can be associated with IP or Tel profiles.
You can select the following coders:
g711Alaw64k – G.711 A-law.
– G.711 µ-law.
g711Ulaw64k
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.
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 – 10,20,30,40,50,60,80,100,120 (default=20).
g723 family – 30, 60, 90, 120, 150 (default = 30).
G.726 family – 10, 20, 30, 40, 50, 60, 80, 100,120 (default=20)
NetCoder family – 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' is enabled.
ini file note 1: This parameter (CoderName_ID) can appear up to 20 times
(five coders in four coder groups).
ini file note 2: The coder name is case-sensitive.
ini file note 3: Enter in the format: Coder,ptime.
For example, the following three coders belong to coder group with ID=1:
CoderName_1 = g711Alaw64k,20
CoderName_1 = g711Ulaw64k,40
CoderName_1 = g7231,90
