Nuisance caller,
Calls on numerous occasions and neglects to leave a message, caller has hidden ID to only show number which appears to be a VOIP number.

We do not accept calls from callers we do not recognize, obviously the call is not important enough for them to leave a message therefore it is not important enough to merit a response. Callers number is also identified on other look-up sites as potential scam or fraud....

p.s.
This number is now on my block list, I also have my phone programmed to download these calls into a data base which records number, time and date stamp of every offending call including those from this number...  simply sharing info here for the benefit of others.
