RPort
This field sets the default port that RTP is using. The port number ranges from 0
(default) to 65535. Setting a value other than "0" for the RPort changes the SIP routing
behavior so that responses can be received through a NAT, even if private addresses
are used in the SIP headers. The Rport should only be changed if the transport is
unreliable.
T1, T2, T4, and TD Timers (ms)
Timer
Default
Description
T1Timer 500 ms
For unreliable transports, such as UDP, the
client transaction retransmits requests at an
interval that starts at T1 seconds and doubles
after every retransmission. T1 specifies an
estimate of the round-trip time (RTT). Nearly all
of the SIP transaction timers scale with T1, and
changing T1 adjusts their values.
T2Timer 4000
ms
Specifies the maximum retransmit interval for
non-INVITE requests and INVITE responses.
For unreliable transports, requests are
retransmitted at an interval which starts at T1
and doubles until it reaches T2. If a provisional
response is received, retransmissions continue
for unreliable transports, but at an interval of
T2. T2 represents the amount of time a non-
INVITE server transaction takes to respond to a
request if it does not respond immediately.
T4Timer
5000
ms
Specifies the amount of time the network takes
to clear messages between client and server
transactions.
TDTimer 32000
ms
Specifies the maximum duration a message will
remain in the network.
Note:
Do not change these timer settings unless you are well aware of their
consequences. Contact the network administrator before changing these settings.
