Planning new install, want to use Centralized CCM and Unity. Multiple remote sites will have inboung calls from PSTN via FXO ports. Want all calls offered an Auto Attendant with cohices for that branch. Easy enough, but does anyone have any ideas for fault tolerance in case of Unity failure or WAN failure? In the case of WAN, we can have the calls just ring local phone via the SRST config. But if the Unity is down how can we know this and redirect the call to a phone instad of Unity. Any Ideas???
