There are at least two options for those bothered by people originating these offensive calls:
1. Go to www.fcc.com and click on the electronic complaint form, filling out each of the entries (takes about two minutes), identifying the date and time of the unwanted call(s), any identifying information from Caller ID ("Unavailable" is a valid entry), your number where the call was received and your name, street and email addresses. The FCC will immediately respond with an email to you, identifying the file number assigned to your complaint. If everyone filed these complaints to the FCC, that deluge will prompt an investigation and likely a fine on the calling party.
2. I followed a recommendation from a comment listed elsewhere on 800Notes, where that person was extremely frustrated over calls from a number different than 360-529-6183 (as the above folks obviously are) and purchased a DIGITONE Call Blocker from www.digitone.com Three features attracted my interest: a) I now can block up to 80 specific telephone numbers, b) This device has "First Ring Supression." meaning that you will not even hear the first ring!!, c) you can block entire area codes, a feature that can be used to block all 800, 866, 877, etc. numbers or those from specific (not toll-free) numbers. There may be other devices available, too. I saw immediate success with the one I purchased.
Silence can be Golden!!
Even so, I regularly report annoying/illegal/robo calls, etc. to the FCC. Now that I also use the DIGITONE device these annoying calls have been greatly reduced in number.
