Note 1: The ptime packetization period depends on the selected coder name.
Note 2: If not specified, the ptime gets a default value.
Note 3: The ptime specifies the maximum packetization time the gateway can receive.
5. Repeat steps 3 and 4 for the second to fifth coders (optional).
6. Repeat steps 2 to 5 for the second to forth coder groups (optional).

Parameter Description
CoderName_ID
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.
g711Ulaw64k – G.711 µ-law.
g7231 – G.723.1 6.3 kbps (default).
g7231r53 – G.723.1 5.3 kbps.
g726 – G.726 ADPCM 16 kbps (Payload Type = 35).
g726r16 – G.726 ADPCM 16 kbps, Cisco mode (PT=23).
g726r32 – G.726 ADPCM 32 kbps (PT=2).
g726r40 – G.726 ADPCM 40 kbps.
g729 – G.729A.
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)
Note: 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
