You set it up to call two phone numbers out of your book and both phones ring with the caller id of your choosing and when they pick up they're. You dial a number provided to you by the service and then enter an access code or PIN number, plus the recipient's number and your fake caller ID. Also like phone calling cards, you buy credits, starting at $4.95 for 25 credits (1 minute per credit).

Caller ID spoofing is the practice of causing the telephone network to indicate to the receiver of a call that the originator of the call is a station other than the true originating station. For example, a caller ID display might display a phone number different from that of the telephone from which the call was placed. The term is commonly used to describe situations in which the motivation is considered malicious by the originator.

History[edit]

Caller ID spoofing has been available for years to people with a specialized digital connection to the telephone company, called an ISDNPRI circuit. Collection agencies, law-enforcement officials, and private investigators have used the practice, with varying degrees of legality.

The first mainstream caller ID spoofing service, Star38.com, was launched in September 2004. Star38.com was the first service to allow spoofed calls to be placed from a web interface. It stopped offering service in 2005, as a handful of similar sites were launched.

In August 2006, Paris Hilton was accused of using caller ID spoofing to break into a voicemail system that used caller ID for authentication.^[1] Caller ID spoofing also has been used in purchase scams on web sites such as Craigslist and eBay. The scamming caller claims to be calling from Canada into the U.S. with a legitimate interest in purchasing advertised items. Often the sellers are asked for personal information such as a copy of a registration title, etc., before the (scammer) purchaser invests the time and effort to come see the for-sale items. In the 2010 election, fake caller IDs of ambulance companies and hospitals were used in Missouri to get potential voters to answer the phone.^[2] In 2009, a vindictive Brooklyn wife spoofed the doctor’s office of her husband’s lover in an attempt to trick the other woman into taking medication which would make her miscarry.^[3]

Frequently, caller ID spoofing is used for prank calls. For example, someone might call a friend and arrange for 'The White House' to appear on the recipient's caller display. In December 2007, a hacker used a caller ID spoofing service and was arrested for sending a SWAT team to a house of an unsuspecting victim.^[4] In February 2008, a Collegeville, Pennsylvania man was arrested for making threatening phone calls to women and having their home numbers appear 'on their caller ID to make it look like the call was coming from inside the house.'^[5]

In March 2008, several residents in Wilmington, Delaware reported receiving telemarketing calls during the early morning hours, when the caller had apparently spoofed the caller ID to evoke the 1982 Tommy Tutone song '867-5309/Jenny.'^[6] By 2014, an increase in illegal telemarketers displaying the victim's own number, either verbatim or with a few digits randomised, was observed as an attempt to evade caller ID-based blacklists.^[7]

In the Canadian federal election of May 2, 2011, both live calls and robocalls are alleged to have been placed with false caller ID, either to replace the caller's identity with that of a fictitious person (Pierre Poutine of Joliette, Quebec)^[8] or to disguise calls from an Ohio call centre as Peterborough, Ontario domestic calls. See Robocall scandal.

In June 2012, a search on Google returned nearly 50,000 consumer complaints by individuals receiving multiple continuing spoofed voice over IP (VoIP) calls on lines leased / originating from “Pacific Telecom Communications Group” located in Los Angeles, CA (in a mailbox store), in apparent violation of FCC rules. Companies such as these lease out thousands of phone numbers to anonymous voice-mail providers who, in combination with dubious companies like “Phone Broadcast Club” (who do the actual spoofing), allow phone spam to become an increasingly widespread and pervasive problem. In 2013, the misleading caller name 'Teachers Phone' was reported on a large quantity of robocalls advertising credit card services as a ruse to trick students' families into answering the unwanted calls in the mistaken belief they were from local schools.^[9]

On January 7, 2013, the Internet Crime Complaint Center issued a scam alert for various telephony denial of service attacks by which fraudsters were using spoofed caller ID to impersonate police in an attempt to collect bogus payday loans, then placing repeated harassing calls to police with the victim's number displayed.^[10] While impersonation of police is common,^[11][12] other scams involved impersonating utility companies to threaten businesses or householders with disconnection^[13] as a means to extort money,^[14] impersonating immigration officials^[15] or impersonating medical insurers to obtain personal data for use in theft of identity.^[16] Bogus caller ID has also been used in grandparent scams, which target the elderly by impersonating family members and requesting wire transfer of money.^[17]

Technology and methods[edit]

Caller ID is spoofed through a variety of methods and different technology. The most popular ways of spoofing caller ID are through the use of VoIP or PRI lines.

Voice over IP[edit]

In the past, caller ID spoofing required an advanced knowledge of telephony equipment that could be quite expensive. However, with open source software (such as Asterisk or FreeSWITCH, and almost any VoIP company), one can spoof calls with minimal costs and effort.

Some VoIP providers allow the user to configure their displayed number as part of the configuration page on the provider's web interface. No additional software is required. If the caller name is sent with the call (instead of being generated from the number by a database lookup at destination) it may be configured as part of the settings on a client-owned analog telephone adapter or SIP phone. The level of flexibility is provider-dependent. A provider which allows users to bring their own device and unbundles service so that direct inward dial numbers may be purchased separately from outbound calling minutes will be more flexible. A carrier which doesn't follow established hardware standards (such as Skype) or locks subscribers out of configuration settings on hardware which the subscriber owns outright (such as Vonage) is more restrictive. Providers which market 'wholesale VoIP' are typically intended to allow any displayed number to be sent, as resellers will want their end user's numbers to appear.

In rare cases, a destination number served by voice-over-IP is reachable directly at a known SIP address (which may be published through ENUM telephone number mapping, a .tel DNS record or located using an intermediary such as SIP Broker). Some Google Voice users are directly reachable by SIP, as are all iNum Initiative numbers in country codes +883 5100 and +888. As a Federated VoIP scheme provides a direct Internet connection which does not pass through a signaling gateway to the public switched telephone network, it shares the advantages (nearly free unlimited access worldwide) and disadvantages (ernet applications).

Service providers[edit]

Customers dial the number given to them by the company, their PIN, the destination number and the number they wish to appear as the caller ID. The call is bridged or transferred and arrives with the spoofed number chosen by the caller—thus tricking the called party.

Many providers also provide a Web-based interface or a mobile application where a user creates an account, logs in and supplies a source number, destination number, and the bogus caller ID information to be displayed. The server then places a call to each of the two endpoint numbers and bridges the calls together.

Some providers offer the ability to record calls, change the voice and send text messages.^[18]

Orange box[edit]

Another method of spoofing is that of emulating the Bell 202FSK signal. This method, informally called orange boxing, uses software that generates the audio signal which is then coupled to the telephone line during the call. The object is to deceive the called party into thinking that there is an incoming call waiting call from the spoofed number, when in fact there is no new incoming call. This technique often also involves an accomplice who may provide a secondary voice to complete the illusion of a call-waiting call. Because the orange box cannot truly spoof an incoming caller ID prior to answering and relies to a certain extent on the guile of the caller, it is considered as much a social engineering technique as a technical hack.

Other methods include switch access to the Signaling System 7 network and social engineering telephone company operators, who place calls for you from the desired phone number.

Caller name display[edit]

Telephone exchange equipment manufacturers vary in their handling of caller name display. Much of the equipment manufactured for Bell System companies in the United States sends only the caller's number to the distant exchange; that switch must then use a database lookup to find the name to display with the calling number. Canadian landline exchanges often run Nortel equipment which sends the name along with the number. Mobile, CLEC, Internet or independent exchanges also vary in their handling of caller name, depending on the switching equipment manufacturer. Calls between numbers in differing country codes represent a further complication, as caller ID often displays the local portion of the calling number without indicating a country of origin or in a format that can be mistaken for a domestic or invalid number.

This results in multiple possible outcomes:

• The name provided by the caller (in the analog telephone adapter configuration screen for voice-over-IP users or on the web interface on a spoofing provider) is blindly passed verbatim to the called party and may be spoofed at will
• The name is generated from a telephone company database using the spoofed caller ID number.
• A destination provider may display no name or just the geographic location of the provided telephone area code on caller ID (e.g., 'ARIZONA', 'CALIFORNIA', 'OREGON', or 'ONTARIO'). This often occurs where the destination carrier is a low-cost service (such as a VoIP provider) running no database or outdated data in which the number is not found.
• If the displayed number is in the recipient's address book, some handsets will display the name from the local address book in place of the transmitted name. Some VoIP providers use Asterisk (PBX) to provide similar functionality at the server;^[19] this may lead to multiple substitutions with priority going to the destination user's own handset as the last link in the CNAM chain.

Legal considerations[edit]

Canada[edit]

Caller ID spoofing remains legal in Canada, and has recently become so prevalent that the Canadian Anti-Fraud Centre has 'add[ed] an automated message about [the practice] to their fraud-reporting hotline'.^[20] The CRTC estimates that 40% of the complaints they receive regarding unsolicited calls involve spoofing.^[21] The agency advises Canadians to file complaints regarding such calls,^[22] provides a list of protection options for dealing with them on its website,^[23] and, from July through December 2015, held a public consultation to identify 'technical solutions' to address the issue.^[21][23][24] Regulators have set a March 31, 2019 target date for implementation of a CID authentication system.^[25]

On December 19, 2018, the CRTC announced that beginning December 19, 2019, phone providers must block all calls with IDs that '[purport] to originate from telephone numbers that do not conform to established numbering plans'.^[26]

India[edit]

According to a report from the India Department of Telecommunications, the government of India has taken the following steps against the CLI spoofing service providers:

• Websites offering caller ID spoofing services are blocked in India as an immediate measure.
• International long distance operators (ILDOs), national long distance operators (NLDOs) and access service providers have been alerted to the existence of such spoofing services, and shall collectively be prepared to take action to investigate cases of caller ID spoofing as they are reported.^[27]

As per DOT, using spoofed call service is illegal as per the Indian Telegraph Act, Sec 25(c). Using such service may lead to a fine, three years' imprisonment or both.

United Kingdom[edit]

In the UK, the spoofed number is called the 'presentation number'. This must be either allocated to the caller, or if allocated to a third party, it is only to be used with the third party's explicit permission.^[28]

Starting 2016, direct marketing companies are obliged to display their phone numbers. Any offending companies can be hit by fines up to £2 million by OFCOM.^[29]

United States[edit]

Caller ID spoofing is generally legal in the United States unless done 'with the intent to defraud, cause harm, or wrongfully obtain anything of value'. The relevant federal statute, the Truth in Caller ID Act of 2009, does make exceptions for certain law-enforcement purposes. Callers are also still allowed to preserve their anonymity by choosing to block all outgoing caller ID information on their phone lines.

Under the act, which also targets VoIP services, it is illegal 'to cause any caller identification service to knowingly transmit misleading or inaccurate caller identification information with the intent to defraud, cause harm, or wrongfully obtain anything of value..' Forfeiture penalties or criminal fines of up to $10,000 per violation (not to exceed $1,000,000) could be imposed.^[18] The law maintains an exemption for blocking one's own outgoing caller ID information, and law enforcement isn't affected.^[30][31]

The New York Times sent the number 111-111-1111 for all calls made from its offices until August 15, 2011. The fake number was intended to prevent the extensions of its reporters appearing in call logs, and thus protect reporters from having to divulge calls made to anonymous sources. The Times abandoned this practice because of the proposed changes to the caller ID law, and because many companies were blocking calls from the well-known number.^[32]

Starting in mid-2017, and with intended culmination in 2019, the FCC pushed forward Caller ID certification implemented via a methodology of SHAKEN/STIR.^[33][34] SHAKEN/STIR are acronyms for Signature-based Handling of Asserted Information Using toKENs (SHAKEN) and the Secure Telephone Identity Revisited (STIR) standards.
