How to develop Fax server?

[Tom]

Receive Fax

1. I need to develop a C# program to listen the incoming fax through DID
modem which supports Class 2.0 - the Post 1992 Standard.

2. After receiving the fax data from modem, the C# program converts fax to
jpg.

Sending Fax

1. Convert MS Word doc file to JPG.

2. Convert MS Word doc file to Fax format and send by modem.

Are there any libraries to do file convertion and communicate with modem?

Or, is there any open source project to do it?
