This is probably a stupid question but, can I plug my landline into my modem/ router and send faxes(files) using Windows Fax and Scan without the use of an external fax machine? I thought of this idea since I'm using a landline connected to a modem/ router it would still work since a landline would still be needed for an external fax machine to send the information to the receiving fax machine.
Also, I'm not sure if this thread (http://forums.verizon.com/t5/Home-Phone-Landline-or-Digital/Verizon-Fax-Service/m-p/231013#M3739) answers my question or not. So if you would like to give it a look at you're more than welcome.
