You didn't say what kind of modem or what kind of phone. However, a 2 line phone ought to be just a switch and a phone; if you don't have your phone picked up on the modem line it shouldn't do anything to your line. You might try making sure only the modem line pair gets to the modem. I've installed modems through RJ-11 jacks and found that the second (supposedly unused) pair gets an incredible hum put onto it by the modem. That is, I have a voice line and a data line and RJ14 jacks (e.g. regular modular jacks where the other line gets put onto the two extra pins.) Some wall jacks have the voice line in the primary slot, some the modem line. I plug the modem into a modem jack and suddenly there's a big hum on the voice line. Never could figure out why. I think this has happened with several different modems. The fix is to get one of these plugs with 3 outputs - line 1, line 2, and both, and plug your modem into a "line 1" jack, which disconnects the line 2 leads. Or do a little wiring to get the same effect. Of course, it goes without saying that if you pick up the phone on your modem line while you have a data call in progress, it will put noise on the line.
