I have come across this problem 3 times now. I always install the Express Messanger VM card in slot 8 of of the first SX200 EL cabinet. About a month from the install date I get a trouble call about customers getting dead are when they call the VM. Ports on the card answer the call but do nothing with it. If I reset the card it fixes the problem but it comes back in a few weeks. When I move the card to another slot I dont see the problem anymore. I was wondering if anyone else has experienced this problem or if anyone knows why it would be happening. Thanx
