CID says FaxHalt. I get numerous calls from this CID. Although I block the number, it changes slightly and still calls. If I pick up the phone, it emits the fax sound which means it is trying to send a fax to my home phone number which has no fax line. Irritating

I, too, receive numerous fax calls from a plethora of numbers that all appear to be from bandwidth.com, a wireless provider,  I block each number and another pops up.  Not just annoying but troubling as I am very ill and the calls come in at the 7am hour and they usually awake me from a much needed sleep.

Always calls in evening around 6pm. Calls every month on the 18th or 19th of the month. Uses 720-386-2911 or 720-386-2777.  

How to get these calls stopped ?????
