Re: Ringing another phone within the house
At risk of sounding like a stuck record:
Get yourself a scrap PC (almost anything new enough to have SATA hard drives will do), 2GB or more of RAM, a multi-way analogue telephone card -- choose very carefully; you need "FXO" ports to connect to an exchange line, and "FXS" ports to connect to a telephone -- and install the Free and Open Source Asterisk software. To use old phones, make sure your FXS ports accept pulse dialling (they usually do; it's almost harder not to). If you have any dial-less CB phones, you can even arrange for Asterisk automatically to dial a number as soon the handset is lifted! You will end up with almost a business-grade phone system, and the "almost" comes entirely from limitations imposed by the exchange line(s) into which it is plugged.
