I have an SX 2000 Light that keeps crashing when it does it's database switch over at 2am. The system is staying down for a few hours before coming back online. The system is located in a part of the country where there are not a lot of good Mitel dealers with SX-2000 experience. We are contemplating disabling the nightly activity switch to avoid downtime, but need to address the real problem. Hardware? Software?
