SIPMaxRtx are sent after 4000 (2*2000) msec. 
Web: SIP T2 
Retransmission Timer 
[msec] 
EMS: T2 RTX 
[SipT2Rtx] 
Defines the maximum interval (in msec) between retransmissions of SIP 
messages (except for INVITE requests). 
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] 
Defines the maximum number of UDP transmissions of SIP messages 
(first transmission plus retransmissions). 
The range is 1 to 30. The default is 7. 
Web: Number of RTX 
Before Hot-Swap 
EMS: Proxy Hot Swap Rtx 
[HotSwapRtx] 
Defines the 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 is 3. 
Note: This parameter is also used for alternative routing. If a domain 
name in the Tel to IP Routing 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.

[CodersGroup9] 
This table parameter defines the device's coders. Each group can consist of 
up to 10 coders. The first Coder Group is the default coder list and the default 
Coder Group.  
The format of this parameter is as follows: 
[ CodersGroup<0-9> ] 
FORMAT CodersGroup0_Index = CodersGroup0_Name, 
CodersGroup0_pTime, CodersGroup0_rate, CodersGroup0_PayloadType, 
CodersGroup0_Sce; 
[ \CodersGroup<0-9 ] 
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,
