I'm looking for a device, perhaps the size of a caller ID box, that can be programmed to block:
800.xxx.yyyy 000.000.0000 'unknown' etc.or anything I desire/program to block.
The only device I could find was this:
formatting link
But I thought $100 was a bit steep.
Is this the only option?
I don't want software (who wants to have a computer powered up with a modem and software analyzing phone calls? Seems a bit inconvenient/sloppy).
