Parameter
Description
voip/signalling/sip/sip_t1
The time interval (in msec) between the first transmission of a SIP message
and the first retransmission of the same message (according to RFC 3261).
The valid range is 100 to 60000. The default value 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..
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 200.
Note:
The time interval between subsequent retransmissions of the same SIP
message starts with SipT1Rtx and is multiplied by two until SipT2Rtx.
voip/signalling/sip/sip_t4
The SIP T4 retransmission timer according to RFC 3261.
The valid range is 5000 to 60000. The default value is 1000.
voip/signalling/sip/sip_in
vite_timer
The SIP INVITE timer according to RFC 3261.
The valid range is 0 to 65535. The default value is 32000.
voip/signalling/sip/sessi
on_timer
The time (in seconds) at which an element considers the call timed out if no
successful INVITE transaction occurs beforehand. This value is inserted into
every INVITE in the Session-Expires header unless it is configured to 0. If the
timer option tag is not part of the supported list, the sessionExpires value is
ignored.
The valid range is 0 to 65535. The default value is 1800.
voip/signalling/sip/min_s
ession_interval
The minimum value for the session interval that the application is willing to
accept.
