Calls and hangs up.

this number called this morning, but the boss answered it before I could. I'm not sure if it was an abandoned call or a robocall, but the boss hung up right away.

This is the latest number in a bunch that have recently called us with this particular caller ID:

Received a call on my 240 area code number. Call was silent, then disconnected. Number is now blocked.
