This looks like the same robo-call system that used to call me from New Jersey, the steam cleaners, although this one is from Salinas. There was no message this time, so it looks like someone is just collecting data on working phone numbers in the area.

I received a call from this number today, I am on do not call list.  It was a steam cleaning recorded message with option to press one to make an appointment.  I did press one and let the person know I was on DNCL and to remove me from their list.  The person said nothing, and then, I think put me on hold.  This caused the line to be engaged, I could not make a call until I left the phone on the hook for over a minute.   I reported it to the DNCL national complaint registry.

Yes, I agree.  Dead silence on the line, and yes, this was previously a mechanized ad-call.  :-(

Spanish-speaking caller, asked to speak to someone who spoke Spanish.

Left no message. They've called before. I have them blocked on my Panasonic phone, so it only rings once.
