I'm hoping someone here has some first-hand knowledge of what I'm looking at getting. I'd like to have an intercom for the exterior entrance into the basement that will ring up the phones down there. A screening process before opening my door is always a good idea, right?

I'm also thinking of buckling and getting a cell phone, but at home I'd rather just pick up a normal phone, so I'd like one of the devices that allows you to link your cell phone to your home phone. The cell phone would actually be my only phone service at that point, no landline, but yeah, a normal phone would be better for me at home. Is anyone currently using one of these?

It wouldn't be hard to integrate both, would it? It would be cool to have distinctive rings for both different callers and for the intercom function. What other features should I be looking for?
