Hi, I'm in the process of trying to figure out how to connect old phone components to a modern gsm shield. And hopefully not fry anything. These are the:
mic and speakers
bell
dial
hookswitch
First I want to start with the speakers and mic. Here is the old phone. The wires look like they are spade style connectors. white and green are for the speakers, red and black are for the mic.
Here is the gsm shield in question. It has only one obvious 'audio' barrel connector that looks like its designed for those audio jacks you find on earphones. Its two in one for both speakers and mic.
My question is how would you 'interface' the old phone connectors with the gsm shield? I don't want to zap my fancy components so I want to be careful.
Here is the schematic for the gsm shield. I can post the schematic for the old phone itself if anyone needs it.
Here is the wiki page for the gsm shield. It claims to take a 5V-12V power supply

Oh and if you have any suggestions about connecting the other components I'd like to hear them too. I think maybe they can be simply attached to individual pins but I haven't worked all the details out.
Thanks
