A:AnswerEach phone weighs 5.1 ounces. You can adjust the volume during a call by pressing the round volume button beneath the display window up or down.
A:AnswerIt works just fine with my HP Officejet which is a printer/copier/scanner/fax machine. The phone line first runs into my Officejet. From there the line goes to the base unit of these phones. So, does your fax machine have both an input and output for the phone line? If so it will probably work fine.
A:Answeryes, just push the green talk button down and your other caller awaits. Push it again and you are back to your first caller. Also if you are are ending your first call you can push the red hand up button and the phone will then ring with your new caller.
