SIP User's Manual 12. Configuration Parameters Reference
Parameter Description
Web: SIP T2
Retransmission Timer
[msec]
EMS: T2 RTX
[SipT2Rtx]
The maximum interval (in msec) between retransmissions of SIP
messages.
The default is 4000.
Note: The time interval between subsequent retransmissions of the
same SIP message starts with SipT1Rtx and is multiplied by two until
SipT2Rtx.
Web: SIP Maximum RTX
EMS: Max RTX
[SIPMaxRtx]
Maximum number of UDP transmissions (first transmission plus
retransmissions) of SIP messages.
The range is 1 to 30. The default value is 7.
Web: Number of RTX
Before Hot-Swap
EMS: Proxy Hot Swap Rtx
[HotSwapRtx]
Number of retransmitted INVITE/REGISTER messages before the call
is routed (hot swap) to another Proxy/Registrar.
The valid range is 1 to 30. The default value is 3.
Note: This parameter is also used for alternative routing using the
'Outbound IP Routing Table'. If a domain name in the table is resolved
into two IP addresses, and if there is no response for HotSwapRtx
retransmissions to the INVITE message that is sent to the first IP
address, the device immediately initiates a call to the second IP
address.
12.10 Coders and Profile Parameters
The profile parameters are described in the table below.
Table 12-28: 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:
