I had this number call me twice now. Once on my old number and then again on my new number. What should I do?

Received an incoming call from this # 5min ago.  Didn't answer. No message left. Thanks to this thread, I know that it wasn't important and not worth calling back.

calls from this spanish number are not wanted

i received a call from this number. googled it. came to this thread. i know it wasn't anyone important. all i know is when the number called it said it was from IA, USA. how do you get these numbers to stop? if they are just a recording (in another language no less) then there is no way to tell them to stop unless you hit the button and if you do that, you are screwed.

Just had a call on my sprint cell phone from 712-986-2323.  I missed the call. They left no message. Its not a number in my personal directory.  Its most likely SPAM.
