Cool! I'm relatively young, so the only interaction I've ever had with a rotary phone was my dad finding one in a box at my grandparents' house. Still, this seems like fun. Cool that you can communicate with the cell modem directly.
It is fun! But I hate people with a lot of 8's, 9's, and 0's in their numbers. They take forever to dial :)
That's when you cheat and just input the pulses with the switch hook by pressing them quickly. 8 times in rapid succession for 8, 9 for 9, 10 for 0.
