[Asterisk-Users] Really Old Rotary Phone

[Sean Cook]

Ok... I am not a telephone guy... I was born after rotary phones, so 
forgive my ignorance in this matter.  I am trying to get a really old 
rotary phone up and running with an ATA.  Why?  Who knows... just 
thought it would be cool. The problem is that it does not have an RJ11 
connector, instead it has three wires (green,yellow,red).  Does anyone 
know what that type of connector is called?  Or know of a reference to 
build an adapter to 2 line?

Thanks,

Sean
