We have two separate cordless phone systems. I upgraded our phones recently (and added one additional extension). We recycles our older Panasonic phone, connecting it directly to the other port of the PAP2T, placing the base behind our TV console, and using the extensions in places we don't typically use the phone (basement, random rooms). Yes, it would have been neat to get a phone with two lines built in, but there would have been a caveat in our case. The PAP2T is in a place where we don't have a physical phone. We plug line 1 into the "house" wiring, and the base is elsewhere. So a two line phone required us to have the base within wiring distance of the PAP2T - not possible for us.

By using both lines, we can make two phone calls at the same time (or answer an incoming call other than using call waiting). Pretty neat. None of my previous providers (Vonage and VoicePulse) offered the free cloned line.
