Do I need to purchase a second call blocker if I have a 2-line phone?

Depends on if you just want to protect the first line only. The Call Blocker is a single line operation. If you need to cover a second line you should purchase a second unit. If you have a 2-line phone and you want to block both lines, then you will need a second Call Blocker. If you have a 2-line phone and only want to block the first line then you only need one Call Blocker using a 4 conductor phone cable. The second line will bypass the Call Blocker system.




The Call Blocker is a single line operation and the 2 conductor line cord supplied with it only carries a single line. If you want to process both lines on your 2-Line phone, then you will need: Two Call Blockers with their supplied single line cords, Two 2-Line Splitters with two single line cords and one Line Coupler. You will use one splitter at the phone wall plate and connect the two supplied single line cords from each Call Blocker to that splitter; L1 to Call Blocker 1 and L2 to Call Blocker 2 then connect the two single line cords from each Call Blocker's TEL phone port to the second line splitter L1 and L2. Connect this splitter to the Line Coupler and then connect the 2-Line phone to the coupler
