Who called from 3109767543

Robodialer.

3/26/15 10:46 PDT  This is the weirdest one yet.  Number shows on caller ID but not on Verizon call log.  Went to voice mail and recorded voice says "you are currently the only person in this conference.  You have been dropped from this conference."  What the heck is going on??  I wasn't home at the time this came thru.

Caller ID said Beverly Hills CA.  Called back and CALL COULD NOT BE COMPLETED AS DIALED.  I am assuming that the number is spoofed or???

Received a call from 310-976-7543 (Los Angeles area) at 3:51pm on a Wednesday. I answered the call, but no-one was there. Call was disconected after 11 seconds.

Caller ID said Beverly Hills CA.  Called back and CALL COULD NOT BE COMPLETED AS DIALED! No big surprise there.
BLOCKED!!!
