>I am developing a Customer Service Software to track customer information. The software must be able to make telephone calls ( been able to use the sound card and the microphone from the computer instead the regular telephone handset), send faxes and receive them automatically. Can somebody knows about a a communication packages that allow me to do that...? Thanks in advanced for any information

I hear that a package called CommTools will do most of what you are looking for. Try looking at www.usa.net/hall/. This is a ad I've seen in the FoxPro Advisor. Might be someplace to start.
