You can administer the system to perform station hunting before the system sends calls to coverage, or after the system sends calls to coverage.
If you administer the system to use Station Hunting before the system uses Call Coverage, the system checks for a hunt-to station at the called extension. If the system finds a hunt-to station at the called extension, the system routes the call down the station-hunting chain. If the system does not find an idle extension in the station-hunting chain, the system routes the call to coverage.
