A friend emailed me the following article URL:
Summary:
TelTech Systems ... is excited to introduce "TrapCall," the first
> cell phone service that unblocks blocked calls, and so much more.
> [...] When a blocked or restricted call shows up on a users cell
> phone, the user just presses the button on the phone that would
> normally send the call to voicemail. The call then loops through
> TrapCall's systems where it's unmasked, then sent back to the user's
> phone, with the caller's number displayed as the Caller ID!
Is that even possible or feasible?
