I use one of these: http://www.homecontr...&category=74261
Telco plugs into it and they can just walk away. Whenever they need a telephone line, they can just plug a Cat5 cable they buy anywhere from here to your patch panel. Plus: built in RJ31X for security panel.
Yea - I looked at that (and ones similiar to it from other brands), but decided to go the cheap route since my only intention is to make it easy for a new homeowner to have working phone lines if needed.
