I have acquired a 70's French Socotel S63 rotary telephone. I have managed to re-wire it so it plugs into my phone socket. It takes incoming calls fine, rings well and has a nice dial tone when I pick up the receiver. However, when I go to dial a number I just get a static sort of noise. It does connect to the number I'm calling but the person on the other end can just here the same noise I can. Does anyone know what the problem might be here?
