Description
Retransmission Timer T1
[voip/signalling/sip/sip_t1]
The time interval (in msec) between the first
transmission of a SIP message and the first

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):
ƒ
The first retransmission is sent after 500 msec.
ƒ
The second retransmission is sent after 1000
(2*500) msec.
ƒ
The third retransmission is sent after 2000 (2*1000)
msec.
ƒ
The fourth retransmission and subsequent
retransmissions until SIPMaxRtx are sent after 4000
(2*2000) msec..
Retransmission Timer T2
[voip/signalling/sip/sip_t2]
The maximum interval (in msec) between
retransmissions of SIP messages (according to RFC
3261).
The valid range is 4000 to 60000.
The default value is 4000.
