Called at 12:09 AZ time.  Did not leave a message.  Tried calling the number back but got no tone.  Waited about 30 seconds and got a busy signal.

I received a call several times recently from this number, too.  (425) 648-9412.

Received a call from 4250648-9412. Caller ID shows JRM Consulting. Did not answer and they did not leave a message

These [***] call 3 times a day.
I called the number back and actually got a prompt to remove my number from their list. however when I select one to removed my number and type it in. It just goes back to the original menu.

Tried to block number through phone company (Vonage) and they do not offer that service :(

These jerks keep calling... today it was FIVE times!  I've been getting "vote for XXXX" voice messages. I feel like calling the candidates who are using this service to tell them to have them stop calling me or I'm not voting for you.  Maybe that will work as their "unsubscribe" option doesn't.
