This was the first type of two-line wall phone that didn't require a heavy cable and a closet full of equipment.
A knob on the front lets you select line #1 or line #2, and if you pull up the knob on the top of the phone, you can hold the caller on one line while you switch to the other line. Built-in mechanical ringer, connected to line #1. If you don't have two lines, you can use this as a one-line phone with hold. New Old Stock. ONE-YEAR WARRANTY. We sometimes have other colors -- call us.
