VR-641
Cisco IOS Voice, Video, Fax Command Reference
sgcp retransmit timer
To configure the Simple Gateway Control Protocol (SGCP) retransmission timer to use a random
algorithm, use the sgcp retransmit timer command in global configuration mode. To restore the default
value, use the no form of this command.
sgcp retransmit timer {random}
no sgcp retransmit timer {random}
Syntax Description
Defaults The SGCP retransmission timer does not use the random algorithm.
Command Modes Global configuration
Command History
Usage Guidelines Use this command to enable the random algorithm component of the retransmi ssion timer. For example,
if the retransmission timer is set to 200 milliseconds, the first retransmission timer is 200 milliseconds,
but the second retransmission timer picks up a timer value randomly between either 200 or 400. The third
retransmission timer picks up a timer value randomly of 200, 400, or 800 as shown below:
•First retransmission timer: 200
•Second retransmission timer: 200 or 400
•Third retransmission timer: 200, 400, or 800
•Fourth retransmission timer: 200, 400, 800, or 1600
•Fifth retransmission timer: 200, 400, 800, 1600, or 3200 and so on.
After 30 seconds, the retransmission timer no longer retries.
Examples The following example shows the retransmission timer set to use the random algorithm:
sgcp retransmit timer random
random Enables the SGCP retransmission timer to use a random algorithm.
