No message. I've saved this number to my caller ID under "scam" so if they call again I'll know to ignore it, or answer the call and repeatedly press the # key to signal the robo dialer that it's a nonworking number.
We received a call this afternoon from the same number, identified as "LEAD," on one of our unlisted phone numbers. As is usual with unknown calls on the unlisted numbers I clicked the phone to answer, placed the phone on the desk while I resumed my work, then disconnected the call after a couple of minutes.
