How to build a 3-way phone
|
|
|
|
Step By Step:
|
|
|
|
1] You will need two different lines for this. Okay first take
|
|
off both of the boxes covering the wires
|
|
|
|
2] Take the green and red from each box and attach a wire to
|
|
each of these one wire to green 1 wire to red same on the other
|
|
box
|
|
|
|
3] After you have 4 wires (2 For each box) then get a two way
|
|
switch with two terminals then hook the two green wires to
|
|
one side and the red wire to the other side then when you
|
|
switch the switch you should here a dial tone and then just
|
|
dial out and you will be able to talk to two people at one
|
|
time
|
|
|
|
[ Note from Tommy: When I was much younger and stupider I tried something
|
|
like this... it worked for about 10 seconds at a time then the audio
|
|
returned from the two far ends of the 3-way started to cancel each other
|
|
out s l o w l y by phase inversion and conversation became impossible...
|
|
if you're going to try this at least put a pre-fabricated FCC Part 68
|
|
interface on each physical line you connect... at least then your own
|
|
incompetence won't draw unwanted attention from your local service
|
|
provider, who I can assure you has significant clout with your local
|
|
police... hint hint, take or leave as you wish... ]
