I get calls from 323-388-5832 in Florida-called back and left msg to leave msg next time and they called back in 10 minutes and left no msg. So I called and left another msg-my I am trouble whistle-Time will tell.LMAO
They could've used an alias or are pretending to be someone else. These calls are most likely being generated online, through Google's Voice service, and are overseas. Majority of these types of calls I've gotten were from China (I actually had someone respond a couple of times and they spoke Chinese), but one came from the Philippines (It was disguised as a call from Arizona, but if you look up the number, it can also be one that is being used in the Manila area). They might be testing something, or are hoping to connect to people who also use similar "phone-by-internet" software, where they can then inject a virus/trojan after making the connection.
