Anonymous Caller? New Service Says, Not Any More

A new service set for launch Tuesday allows cellphone users to unmask the Caller ID on blocked incoming calls, obtaining the phone number, and in some cases the name and address, of the no-longer-anonymous caller.

The service, called TrapCall, is offered by New Jersey's TelTech systems, the company behind the controversial SpoofCard Caller ID spoofing service. The new service is likely to be even more controversial — and popular.

Consumers have had the option of shielding their number from display since Caller ID was introduced in the early 1990s, either by dialing *-6-7 before placing a call, or asking their carrier for blanket anonymity for their line. But TrapCall takes advantage of a loophole in Caller ID blocking that’s long benefited corporate phone customers: Namely, calls to toll-free numbers are not blocked, because those calls are paid for by the recipient.

TrapCall instructs new customers to reprogram their cellphones to send all rejected, missed and unanswered calls to TrapCall’s own toll-free number. If the user sees an incoming call with Caller ID blocked, he just presses the button on the phone that would normally send it to voicemail. The call invisibly loops through TelTech’s system, then back to the user’s phone, this time with the caller’s number displayed as the Caller ID

TelTech is no stranger to controversy. Its Spoofcard product lets customers send any phone number they want as their Caller ID. Among other things, the spoofing service has been used by thieves to activate stolen credit cards, by hackers to access celebrities’ voicemail boxes, and by telephone hoaxsters to stage a dangerous prank called "swatting," in which they spoof an enemy’s phone number while calling the police with a fake hostage situation. The goal of swatting — realized in hundreds of cases around the country — is to send armed cops bursting into the victim's home.

He also expects his new business will be good for his old one.

“The only way to block your number after this is released is to use Spoofcard,” he says with a laugh.

Sounds like the premise of a Philip K. Dick novel.
