The 3 lines in question are all on the expansion card of the Partner system. I have swapped out the ACS, the 308EC, the carrier, and even the VM. I have tried arranging a meeting on site with Qwest, but the problem is sporratic so its been tough. It happens anywhere from 3 or 4 times a day to 30 or 40. I have tested at the demark with all equipment disconnected and have had the same problem. The problem is when they go out and check they stay for 5 minutes and say its working fine and they leave. I'm sure its their problem, I just don't know how to prove it to them.
