Same story to me as Wild Man. I heard a beep twice from the 206 (seattle), I hung up. Beep again from 312 (chicago) and sent both to my Call Blocker Gold for my droid. PS if you have Call Blocker Gold make SURE you uncheck silence first ring. My HTC1 wouldn't friggin ring and I couldn't figure out why. Turns out this awesome app has the most trolling feature that's defaulted to on. Lucky I found it before I got a new phone.
I get repeated calls from the same two numbers:
312-299-0981
206-588-7246
If one calls then the other follows shortly. I believe they are fax numbers. The calls are repeated so many times that I cannot use my lines for incoming calls.
