When the number is called we just get a disconnected phone message, but it doesn't sound  "right".  Its more than likely the National Security Agency doing sneaky things that we would never approve of. Google  'Infinity Transmitter' and thats probably what they're doing with your phone.  Loose lips sink ships. . .

Several calls a day!  

I'm having the same problem.  Someone suggested they may be checking to see if anyone is home.

Number seems to be assigned to

Geri L Weber
310 Leland Rd
Bay Point, CA 94565
(925) 439-8581

Unless it's being spoofed.

Same as everyone else-----they call every day and never leave a message. The one time I did answer, there was nobody there. I'm on the Do Not Call list but obviously it's not working.

i got an actual person this time and interrupted and said put me on do not call list and they hung up on me.

They call almost daily - I do not answer EVER - I could not care less what they want.  It is hard not to seriously wish them harm for being such a persistent, intrusive, irritating presence.

no message left.

First call from this number (925-493-8581) - nominally from Pittsburg Calif.
Silence, then a beep, then disconnect.
However, same area code and exchange (925-493-8548) has called here multiple times.
Usually the same silence, beep, disconnect - so it may be the same scammer with a new number.
However, one time a man got rude with my answering machine - very odd.

This number calls my "Do Not Call" listed number all the time!  I'm sick of it & NEVER answer!!  STOP IT!!!
