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 |
| random | Enables the SGCP retransmission timer to use a random algorithm. |

12.0(7)XK | This command was introduced on the Cisco 3600 and |
| Cisco MC3810 multiservice concentrator in a private release that |

| available on the Cisco 3600 series router and the Cisco MC3810 |
| multiservice concentrator |

Usage Guidelines Use this command to enable the random algorithm component of the retransmission 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.
