In fact, late last week, the CTIA wrote the FCC to tell it that the kind of blacklist approach taken by Foss’s company wouldn’t work. According to the lobbying group, it raises privacy concerns—and causes other problems too.
“Even assuming an accurate database of blacklisted and whitelisted numbers can be compiled and maintained, the ease with which modern equipment and software can allow a caller to spoof a caller ID would present significant challenge,” the group says.
I thought the phone companies had access to more information than caller ID for the calls they handle. Surely you can't fake caller ID details to dodge your phone bill? I'd love it if they'd give out a star code we could all dial after a call we didn't want to receive that would, if enough people did it, disallow future calls from that entity from reaching any phone line for which a customer has requested the blocking of calls reported as bothersome. No exemptions for charities or politicians either.
