Hey,
About a month and a half ago I came accross this a very strange dynamic test message while war dialing, telling me something about voltage level. Today I was outside and I wanted to see if it still works. I call with a pay phone and I hear the same recording. I hang up and my money comes back. I think to my self "Wow, that's really neat!" I call again with a different payphone, except this time at the end of the call I can't get my money back. They were both Verizon payphones. What's up with this? Why was the supervision of the second call different?
