I have a Dimension 4100 with a U.S. Robotics 56K Voice PCI modem.  I am in the process of deciding on a new computer.  However, it doesn't appear that they come with a voice modem anymore.  My husband is a quadriplegic and he uses the modem to dial out on the phone which thus uses the speakers and microphone for the computer.  I am wondering if it would be possible to use the modem that is in this computer in a new computer or is there a better solution.
