Have a phone in kitchen another one in the bedroom. Using the same land base line.
Is it possible to get buzz from the kitchen phone to the bedroom phone? So I know
The call is for me??

I remember phones that could do that (I assume a person will buzz you, right?), but you may have to find a used one on eBay. Look for at least an intercom feature. You might find a new one in Walmart or Radio Shack, not sure.

Great Idea. Intercom. Maybe they make wireless

I would check the features on some of the newer phones. While it's such a big thing now for satellites throughout the home, I'm sure some could do what you are asking for.

Many of the inexpensive wireless phones with a single landline base phone have intercom capabilities. Here is one with three phones all with intercom http://www.target.com/gp/detail.html/185-0807952-1247340?asin=B001W0Y4D6&AFID=Froogle_df&LNM=|B001W0Y4D6&CPNG=&ci_src=14110944&ci_sku=B001W0Y4D6&ref=tgt_adv_XSG10001
