After receiving more than my tolerance level of these #'s, I check the # on the phone to assure that isn't anyone pertinant and answer...
"Such-and such" regional / State police, if you know the officer you wish to speak to, I will be glad to direct your call".... "Please hold"
   ' works every time....they never call back.
   You, for legalese purposes, must not use the name of a legitimate police force.

The caller wanted to clean my ducts.

I received a call from this number about duct cleaning.  The caller did not state the company name and hung up when I began to ask them not to call again before I could finish my sentence.  I filed a complaint with the CRTC do not call registry as my number has been registered more than 1 year.

Rec'd two calls and when you say hello twice in a span of 15 seconds they just hang up.  Nobody responds on the other end of the line, more of an annoyance than anything else.  I've coded my phone to identify this number as a SPAM CALL - don't answer

Got a call from this number but could only hear static. I have added it to my Panasonic phone that has a block list. If they call back my phone ring 1/2 times and hangs up on the call.
