10.10 Coders and Profile Parameters
The profile parameters are described in the table below.
Table 10-30: Profile Parameters
Parameter Description
Web: Coders Table/Coder Group Settings
EMS: Coders Group
[CodersGroup0]
[CodersGroup1]
[CodersGroup2]
[CodersGroup3]
[CodersGroup4]
This ini file table parameter 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:
9 [0] Disabled (default)
9 [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 ]
