SIP User's Manual
Description
Enables / disables the usage of the SIP Reason header.
Disable [0].
Enable (default) [1].
Determines the gateway behavior when Transfer is initiated while still in Alerting
state.
Valid options include:
Send REFER with Replaces (default) [0].
Send CANCEL, and after a 487 response is received, send REFER without
Replaces [1].
Determines the gateway's behavior when a 3xx response is received for an
outgoing INVITE request. The gateway can either use the same call identifiers
(CallID, branch, to and from tags) or change them in the new initiated INVITE.
0 (forward) = Use different call identifiers for a redirected INVITE message
(default).
1 (redirect) = Use the same call identifiers.
The time interval (in msec) between the first transmission of a SIP message and
the first retransmission of the same message.
The default is 500.
Note: The time interval between subsequent retransmissions of the same SIP
message starts with SipT1Rtx and is multiplied by two until SipT2Rtx.
For example (assuming that SipT1Rtx = 500 and SipT2Rtx = 4000):
The first retransmission is sent after 500 msec.
The second retransmission is sent after 1000 (2*500) msec.
The third retransmission is sent after 2000 (2*1000) msec.
The fourth retransmission and subsequent retransmissions until SIPMaxRtx are
sent after 4000 (2*2000) msec.
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.
Number of UDP transmissions (first transmission + retransmissions) of SIP
messages.
The range is 1 to 7.
The default value is 7.
