The simplest and cheapest PBX-like device?

I am trying to find a communications solution for two elder relatives of mine. They live next to each other in a place where phone calls are expensive, even local ones. I have considered a couple of "intercommunicators" which have to be plugged only to the AC power, and the voice is modulated by the 110v. signal, with no need for a data cable. The problem with this solution is that the two homes don't share the electrical circuit. I would like the communication to be full duplex, too. Are there full duplex wireless phones?

Finally, what about a tiny, inexpensive, 2 line PBX? Is there such a thing?

Thanks so much for your kind assistance, my two aunts will appreciate it, too.

What distance is next to each other? Why not run a telephone cable or use an extended range multihandset wireless telephone?

If you can run a direct wire between them, there are two ways to solve the problem:

  1. Construct an intercom circuit and use separate phones
  2. Use "Field" phones like the Army sells surplus

Probablhy. Something with handset to base communications. I have a Panasonic with dual handsets, but I've never really tried to communicate handset to handset.

Of course. You probably need to be within 500 feet and need 4 wires to make the really inexpensive Tie 612/616 blue boxes work. Probably $50 and a few buxks shipping could get you a cabinet and 3 phones.

A pair of inexpensive FRS radios with PL (tone encoding), maybe even a digital xmit mode.

You can use IP-telephony, a tiny asterisk installation and a few handsets. You may use WiFi to reach the other party.

Another solution is a DECT bridge between two DECT base stations.

Both of these have ranges of a few hundred meters if you install them right.

Use radio if you can.

Do not even bother with Asterisk unless you are a total Linux geek!

my suggestion is very simple . If you can get a cable run between the two locations, simply get a Sipura , Linksys or other 2 port ATA used for IP telephony. Make sure it is NOT a model that is locked to a provider

give it a fixed IP address if there is no internet available.

In the case of a single ATA with 2 ports, you can set it up in the dial plan so thart when 1 is dialed for instance the ATA dials and on the other line that when 1 is dialed is dialed. . this way they need only lift the handset and dial 1 This can be m odified for 2 separate devices by modifying the IP addresses.

Alternately, if broadband is available, you can get a dual port ATA and set up two accounts on, or then each will have an extension available worldwide.
