Profile Parameters
CoderName_ID
[Coder Group Settings] 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.
g711Ulaw64k – G.711 µ-law.
g7231 – G.723.1 6.3 kbps (default).
g7231r53 – G.723.1 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.
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 family – 10, 20, 30, 40, 50, 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 will 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.
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: CoderName,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
