We are on a Fiber connection through our phone system now. I don't know the phone system model being used right off, but it runs all our incoming phone lines with a rotary hunt type setup, and then provides ISP service over fiber ports built into the unit that comes out Ethernet to our routers. It is all suppose to be static IP's as well.
Thanks for the other information, I'll check the stuff out, but an initial response from D-Link support...they didn't know right off and wish for me to call them directly. Perhaps they wish to Bomgar in, or some remote session to investigate. I have not done that just yet, and was seeing if anyone in the forum has had the same problem as I. T
