Who called from 4432017453

Caller ID had "Westminster" [MD] on my office line. No response on pickup, so I hung up.

I've gotten a call twice within the past two days.  I call and the line is busy.

this number called twice , I did a return call no one answers and it is busy signal

Received a call from this number; no response to my answering the call.  Call back and get the msg that long distance charges pertain to this call please dial '1' before the number.

I received two calls from this number on March 4, 2016 and one call today. The caller is "Unknown" and has never left a message. "Mr. Call Blocker" will respond the next time and they can chat with "him". Lol !!!
