Everyone look for the company and there board of directors. Then we can ALL turn this around on them. I have found out so far-----
The phone carrier is Broadwing Communications LLC in OH some fly by night.
Every one keep looking and post what you find
There is an option I found on my android phone to send calls from a particular entry directly to voicemail. Presume you can do something similar on iPhones and maybe other smartphones. Made an entry called spam Crap Telemarketer and now I add each new number they call from to that entry which is marked to go straight to voicemail. Also put a minimal ringtone on it, silence would be better.
received a call from these folks and have, over the years of having been on a no-call list, tried to listen to the message and select the option to be taken off the list, have waited to talk to a person, and have tried calling the caller-id number (which changes periodically) back to find the voice mailbox as full... these people deserve both scorn and pity; is there, perhaps, a business opportunity here in the form of a private agency that collects phone call complaints and then, with tenaciousness and vigor, investigates the location(s) from which calls are being placed, finds the business registration(s), identifies the principal(s) and then files civil and (where possible) criminal lawsuits? seems to me that a private, or set of private, companies who help track down these obnoxious and miserable people and prosecute to the fullest extent of civil and criminal law would work to make this sort of endeavor less-than-profitable... add in a policy of full disclosure and publication of all civil and criminal actions, including names, locations, dates, etc. and the public shame element would also work to counter the attractiveness of this sort of activity... think of it like a public wall of telemarketing shame...
