Who called from 2150113259

This number called me twice today.  When I pick up no one talks then they hang up.
I'm on the "no call list."

number called me today, did not recognize it, so I didn't pick up.

Received call but didn't answer b/c didn't recognize number.  This code came on id
V40310015600036. What does that mean?

I keep getting calls from this number. A message is never left, and when I do answer, the caller hangs up.

this number called me twice today......someone is there but says nothing....so the second time i didn't answer
