Can you recommend a library for .NET that can receive FAXes? Window Fax server is not enough - need to auto process and route the Fax once it is received based on the incoming Caller ID.
Could you use a system which automatically routes faxes to email, and then make your .NET code just process emails? That would separate out your processing from the fax side of things. Aside from anything else, it would make it a great deal easier and cheaper to test.
It may not be the most efficient way of processing faxes, but it's practical.
