Who called from 2487559949

Didn't recognize so let it go unanswered, got no vmail message afterward

Same as the above.

I just received a call from this number, I did not answer and they did not leave a message. I returned the call 4 minutes later only to receive a 'disconnect message' that this number was no longer in service - lol, that was quick! SCAM!!!!

Got a call from this # 7:52 am California no message didn't answer.

Rec'd call 8:00 am PST.  Recorded message said "That is not a valid extension." and hung up.  Obvious scam call, but could they just be trolling for numbers and electronically keeping track of who answers?
