Please add the ability to schedule "maintenance windows" where a Passive Enterprise Edition will not initiate failover. Currently both the the Active and Passive options on both servers needs to be manually disabled on both PBXs, maintenance performed, and then manually enabled again on both systems. This can lead to errors and increases administrative burden. Schedule options should include Start date/time and duration in minutes/hours. There should also be an option to repeat the schedule. (None, Daily, weekly, monthly.) For example, and organization could schedule maintenance mode from midnight to 3am Daily, allowing server reboots, patches, and other updates to occur without causing a failover event. If the Active server is not available after the window expires, a failover should occur.
