/mcpExample admin:set sip-trunkbusyout enable This command makes all the SIP Trunks respond to the OPTIONS request message with a '503 Service Unavailable error. This is a clusterwide command. A Cisco CallManager service restart is not necessary.
Warning: If OPTIONS Keepalive/Ping is enabled for peer SIP clients such as Unified CM, IM and Presence Service, Cisco Unified Border Element, or Unity Connection, activating this configuration renders the SIP Trunk for this cluster non-operational on those peers. This may result in call failures, call rerouting, and other operational impacts. Existing calls continue to be active until it is terminated. This command has no impact if OPTIONS ping/keepalive is not enabled in your deployment.
