Wiring a payphone to cell phone
WeeBo:
Hello, long time lurker first time poster.
I thought this would be a great place to ask, I googled a bit on a the topic but the results were crap.
I acquired an older Bell payphone, did as much as I could with exploring the innards, but now I need to do more with it. I have a few spare cell phones. My idea was to stick a cellphone inside and be able to use the handset and dial pad on the front of the payphone. Reception might be a little iffy, but I was thinking of using the outer shell/housing as a make shift antenna.
I was thinking of using the handset to audio jack hack inside the case, and wiring the buttons to the stripped down push pad inside the cell phone, alas at the moment all I have are touch screen phones that work, wonder if that would still be possible. I think hanging up and making the phone ready to dial might be a challenge, as the number has to be dialled before the call button can be pressed.
The hanging up could be controlled by wiring the cradle to the actual hangup button, so when the receiver is put down the contact is made to the hangup/power pad on the stripped down phone.
If anyone has any ideas or suggestions please feel free to contribute, still don't know if I'm making this more comlicated than I have to :)

Welcome to the forums!
http://phonelabs.com/prd05.asp this thing looks old and I didn't read much of the page, but I think products like this still exist for more modern cell phones, where you can put your cell phone into a dock when you get home and it runs all of your home phones from your cell phone.
You might also consider doing all of this with some kind of a blue tooth controller instead of an actual cell phone.
The way I run my pay phone is by using MagicJack. It's $20/year for a VoiP line with unlimited everything. I know that has nothing to do with what you're asking, but that could be another option if you just want your pay phone to work.

Hi rbcp,
I've looked into the cradles/docks as well (that page in particular was one of the products), but I thought that would be too easy. :)
I thought of putting all the guts in the coin change box since than I just have to take out the box and change the battery that way, leaving it "wireless"...unless the handset won't work without some sort of power, but I think the 3.5mm jack should be plenty.
I also think that I will have to use either the # or * key to actually dial the number...but I might miss those keys :(
I have a few cdma phone laying around that I want to use since than I can just keep everything one number.
EDIT - I didn't think of the ringer....crap.

Hey, thanks for the suggestion as well. Both of the products mentioned by you and rbcp are great, but the idea is _not_ to use them. That's the challenging part :)
It's more interesting when you take shit apart and figure it out yourself :) Where is the fun of just plugging something in :)
