Same thing, very disruptive as I am extremely busy in this office.  If it is solicitation I will take the call and kindly ask that we are taken off the list.  Frustrated.

Received a "automated" mechanical call from this number that after a long pause then after just enough tiime to be really annoying you get a mechanical Goodbye !   ??

They called me twice today. No one spoke. Very disruptive as this is a business and i have better things to do than answer calls from morons.
