Rotary Cellphone
I use an unmodified rotary phone as my main landline phone. In the UK it would seem that our exchanges still support pulse dialling. The only drawback are menu systems that expect to hear tones, but I get around this with a small app on my mobile phone that just plays DTMF tones. If i want to, i can pick up the receiver and play tones down it to dial a number rather than using the... dial.
