It's very difficult to block the calls from this company as they call from a different spoofed number each time. I've recorded eight different phone numbers for the exact same recorded message:

602-238-7719
309-717-0079
310-935-4514
973-870-0618
909-947-3654
949-298-8008
714-904-4294
323-736-4027

Robocall, woman's voice: "Hello! The state has determined that you qualify for a new energy release program where you may be eligible to receive up the a $21,000 tax credit. Press 5 for additional information. Press 3 to no longer receive these calls."

Needless to say, pressing any number will not stop the calls.
