NUISANCE CALLER
The offending caller began calling our number months ago and calls numerous times throughout the week.  They obviously don't feel that their call is important enough to leave a message so it's certainly not important enough for me to answer.   Caller ID only provides a number and does not reverse resolve to the caller's name or identity,  which leads me to suspect this is a spoof number, VoIP or the ID is intentionally blocked on the callers end.   There is absolutely no reason for a legitimate caller to hide their identity therefore it leads me to believe that this caller is up to something nefarious.

My phone is set up to automatically block this call and numerous other numbers by pushing the call  to a dead end voicemail and documenting the call data in a database for potential future legal actions against defendant caller.
