h225 alt-ep hunt
To configure alternate endpoint hunts for failed calls in an IP-to-IP gateway (IPIPGW), use the h225 alt-ep hunt command in H.323 voice-service configuration mode. To control the alternate endpoint hunts based on call disconnect cause codes, use the no form of this command.

Usage Guidelines
The default behavior of the gateway is to retry all alternate endpoints received from the gatekeeper regardless of the ReasonComplete reason. Only the no alt-ep hunt command will be visible in the configuration. A code returned from the destination router to indicate why an attempted end-to-end call was unsuccessful. If the specified disconnect cause code is returned from the last destination endpoint, dial peer hunting is enabled or disabled. You can enter the keyword, decimal value, or hexadecimal value.
The disconnect cause codes are described in the table below. The decimal and hexadecimal value of the disconnect cause code follows the description of each possible keyword.
