4.2.6.6.3 SIP Timers Parameters
Table 4-21: SIP Timers Configuration File Parameters
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):
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..
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.
The valid range is 0 to 65535. The default value is 900.
4.2.6.6.4 SIP QoS Parameters
Table 4-22: SIP QoS Configuration File Parameters
Parameter Description
voip/signalling/sip/tos QoS in hexadecimal format. This is a part of the IP header that defines the
type of routing service to tag outgoing signalling packets originated from the
phone. It informs routers that this packet must receive a specific QoS.
The default value is 0x60.
Values can be set in decimal (e.g. 96) or hexadecimal (e.g. 0x60).
