The simplest and cheapest PBX-like device?

Discussion in 'VOIP' started by Ramon F Herrera, Jan 31, 2007.

  1. 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

    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?

  4. Ramon,

    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.

  7. 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

    Use radio if you can.
