 ### -FailoverTimeSeconds
 When set to 10 (default value), outbound calls that are not answered by the gateway within 10 seconds are routed to the next available trunk; if there are no additional trunks, then the call is automatically dropped. In an organization with slow networks and slow gateway responses, that could potentially result in calls being dropped unnecessarily. The default value is 10.
