How might I call another phone on the same landline? Answered

Just wondering if there was a way to make the other phones in the house ring using a landline with no call waiting. I live with my elderly grandparents who can't always make it up the stairs to get a hold of me...

The phones I just installed tonight have a nifty and intuitive intercom feature. My wife loves it especially... I wonder if they'll take returns...

To be practical, you need to design and build a PBX

There are instructions and schematics available online in various places. A word of caution, they tend to become expensive projects and rarely prove their worth.

There are FM intercoms that plug into your house wiring - and use your existing wiring to transmit. They offer a 'page tone' button, and a transmit/transmit lock button. You hit the tone button, and it transmits a buzz over all intercoms in the house - Then it's a push-to-talk half duplex communication system. You don't have to page before talking, but the page gets the receiving party's attention.

I should note - we use one between our kitchen and detached garage. (home theatre in garage loft :D) people inside can notify people in the garage of important stuff like 'the pizzas here'...etc.

There is a way, if you can understand how your phone system works. This might be useful:
