I have connected a 2-wire phone cord to my HP Officejet 4650 all-in-one in the #2 line socket. I have an Xfinity XB6-T internet modem with 2 line sockets , #1 is the phone line coming in, amd the #2 is empty. Can the #2 socket on the XB6-T be used for the fax line, directly connected to the 4650?
I do not have a second #(can't afford), but I have a special ringtone for incoming faxes. The modem I use is an xfinity CGM4140COM, and my Printer/fax is compatable. To connect the 4650 to the modem , should I plug in the 2-wire cord into the modem's #2 port?
