This is a strange issue. We have a BCM 200 with a digital line card installed with 12 lines (the other 12 are for data). Gradually , throughout the day the lines will fill up and we will begin to get "all lines are busy" both on the caller side from outside and the internal callers. When I open the BCM monitor it shows several of the lines with a ? by them saying connected.. I posted a screen shot of my BCM monitor on the web to see if anyone could help understand what was happening. can you tell me if there is a way to remotely disconnect lines in the system through the BCM monitor?
