Parameter Description
Coders Table
[CoderName]
This ini file table parameter defines the device's coders. This includes up to
five groups of coders (each group consisting of up to five coders) that can
be associated with IP or Tel Profiles ('Coder Group Settings' page in the
Web interface -- refer to ''Coder Group Settings'' on page 107). The firs
t
group of coders (indices 0 through 4) is the default coder list and default
coder group. The format of this parameter is as follows:
[CoderName]
FORMAT CoderName_Index = CoderName_Type,
CoderName_PacketInterval, CoderName_rate,
CoderName_PayloadType, CoderName_Sce;
[\CoderName]
Where,
 Type = Coder name
 PacketInterval = Packetization time
 Rate = Packetization rate
 PayloadType = Payload type
 Sce = Silence suppression mode
For example:
CoderName 0 = g711Alaw64k, 20,,,0;
CoderName 1 = g726, $$, 3, 38, 0;
CoderName 2 = g729, 40, 255, 255, 1;
