We have a service that converts our incoming faxes to PDF. After several years and due to the increasing volume (dozens of faxes per day) the costs are spiraling (redirected incoming faxes to the fax-pdf provider and fees of the fax-pdf provider). Therefore a provider is not an option and redirecting isn't either as we already have this.
I want to set up an old PC with a modem and software that converts the incoming faxes to PDF's and stores them in a network directory. I need a recommendation of a good piece of software for doing this.
