After mucking around, I finally found the problem, which may be a common one. The telephone and modem only use two of the wires in the 4-pin connector. The modem considers the other two to be a data control signal. My phone didn't do anything with these wires, but it did have them both attached to the same otherwise unused screw terminal - it had connected them together. I moved one of the wires to another unused terminal, and the problem with the modem vanished. Ma Bell, etc. would prefer you didn't fiddle with your phone, so you can do the same thing by cutting one of the wires in your modem cord (or disconnect it inside the modem). Hope this helps.
