Parameter Description
Web: Coders Table
EMS: Coders
[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
162 ). The first 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,
ƒ
Type = Coder name
ƒ
PacketInterval = Packetization time
ƒ
Rate = Packetization rate
ƒ
PayloadType = Payload type
ƒ
Sce = Silence suppression mode
For example:
CoderName 0 = g711Alaw64k, 20,,,0;
CoderName 1 = g726, $$, 3, 38, 0;
CoderName 2 = g729, 40, 255, 255, 1;
