Several clients have expressed an interest in getting a blocking service to prevent junk phone calls from being received on their land lines.
Is there a filtering service that can work with VOIP provided by Xfinity, FIOS, Optimum Online, and other providers?
Is there one for those using copper wiring?
I have been using RoboKiller on my iPhone, and I've been happy with that service.
Something like that for land lines would be great.
