Command Reference Guide
ip sip timer
Use the ip sip timer command to configure the Session Initiation Protocol (SIP) initial round trip timer
(RTT) estimate (T1 timer) and the maximum retransmit interval for nonINVITE requests and INVITE
responses (T2 timer). Use the no form of this command to return to the default value. Variations of this
command include:
ip sip timer T1 <value>
ip sip timer T2 <value>
ADTRAN does not recommend changing T1 and T2 timer values. T1 and T2 timers are
base timers within the unit, and any changes will affect other timers which are based off of
these timers.
Syntax Description
T1 <value>
T2 <value>
Default Values
By default, the T1 timer is set to 500 milliseconds, and the T2 timer is set to 4000 milliseconds.
Command History
Release 13.1
Usage Examples
The following example configures the T1 timer to 1000 milliseconds:
(config)#ip sip timer T1 1000
60000CRG0-35E
Specifies the T1 timer. This timer is an estimate of network round trip time,
and is used as the initial request retransmit interval. Several other SIP
timers are derived from the T1 value. Valid range is 50 to 1000 ms.
Specifies the T2 timer. This timer is the maximum retransmit interval for
non-INVITE requests and INVITE responses. Valid range is 1000 to
32000 ms.
