We have a BCM 400 with 3.7 software. The system is running well except the manager becomes unaccessable at times. After a reboot we can access the manager and call pilot but a few days later it will lock up again. We noticed DNS was enabled and immediately disabled that parameter and thought we fixed the problem but it locked up again after about two days. We are using Lan 1 for public IP and Lan 2 for the private IP. We are using Unified Messaging on Lan 2 and the IP phones are connecting to Lan 1. Are there any setting on our server that are in conflict wthi the BCM?
