Who called from 2392495049

received a call from this number early in the morning. calle it back and the number drops. who is making this call?

Anyone know who this is? They number keeps calling and hanging up as soon as you answer it. When you call it back you just get a busy signal.

My sister called me this morning and this was the number on my caller ID.  I almost didn't answer the phone, but when I did, it was my sister.  I asked her what phone she was calling me from and she was using her cell phone.  I have NO idea why this number showed up and it is clearly not her number!!
