Table A-33: Profile Parameters
This parameter table defines the device's coders. Up to five groups of coders
can be defined, where each group can consist of up to 10 coders. The first
Coder Group is the default coder list and the default Coder Group. These
Coder Groups can later be assigned to IP or Tel Profiles.
The format of this parameter is as follows:
[ CodersGroup0]
FORMAT CodersGroup0_Index = CodersGroup0_Name,
CodersGroup0_pTime, CodersGroup0_rate, CodersGroup0_PayloadType,
CodersGroup0_Sce;
[ \CodersGroup0 ]
Where,

Index = Coder entry 0-9, i.e., up to 10 coders per group.

Name = Coder name.

Ptime = Packetization time (ptime) - how many coder payloads are
combined into a single RTP packet.

Rate = Packetization rate.

PayloadType = Identifies the format of the RTP payload.

Sce = Enables silence suppression:

[0] Disabled (default)

[1] Enabled
For example, below are defined two Coder Groups (0 and 1):
[ CodersGroup0 ]
FORMAT CodersGroup0_Index = CodersGroup0_Name,
CodersGroup0_pTime, CodersGroup0_rate,
CodersGroup0_PayloadType, CodersGroup0_Sce;
CodersGroup0 0 = g711Alaw64k, 20, 0, 255, 0;
CodersGroup0 1 = eg711Ulaw, 10, 0, 71, 0;
CodersGroup0 2 = eg711Ulaw, 10, 0, 71, 0;
[ \CodersGroup0 ]
[ CodersGroup1 ]
FORMAT CodersGroup1_Index = CodersGroup1_Name,
CodersGroup1_pTime, CodersGroup1_rate,
CodersGroup1_PayloadType, CodersGroup1_Sce;
CodersGroup1 0 = Transparent, 20, 0, 56, 0;
CodersGroup1 1 = g726, 20, 0, 23, 0;
[ \CodersGroup1 ]
The table below lists the supported coders:
Coder Name Packetization Time
