Who called from 2153524907

TELECOMMUNICATIONS TERRORISM
Persistent caller who never leaves a VM, but always hangs up if I answer.
Suspect this is an automated dialing program probing numbers to validate active lines for telemarketers and other scammers.
This number is now on my black list, phone system is set up to blackhole future calls from this number and automatically document info into a database for potential legal action.

Called last night at 8:27PM.  No message of course.  Blocked the number but they easily change their numbers to call again.

Called me, I didn't recognize# so I didn't answer.  No VM.  I blocked it.
