Received a call from this number at 5:07 PM. After I answered "Good evening, this is ----," a female voice began rapidly speaking in Spanish non-stop for about 20 seconds. I don't speak Spanish, so I tried to cut in with English so she could discover I couldn't understand a word she said. No luck. Finally she stopped speaking and I told her I couldn't understand anything she was saying. She did not speak again during the next 5-6 seconds, and I hung up the phone.
At first I thought it was a wrong number, but considering the time of day, overall feel of the call, the fact this phone number was just registered in Jan 2015 (thank you Google), and with one existing report of "spam call in Spanish - don't answer" from callsme.info, this was clearly not a legit call.
I've blocked the number and added it to my "Do Not Answer" list.
