The United States is making a significant feat in the fight against bots, but the annoying calls aren't stopping anytime soon

Large carriers publish STIR / SHAKEN. Small carriers and old fixed lines still have problems.

The nation's major phone companies have called for a federal deadline to introduce new anti-bot technology, but spam calls and scams remain a vexing problem for Americans for the foreseeable future.

"The largest voice service providers are now using the STIR/SHAKEN caller authentication standards on their IP networks, according to the FCC's [June 30] deadline," FCC Chair Jessica Rosenercel said Wednesday. This helps protect consumers from fraud. Illegal calls and help law enforcement track down bad actors.

STIR/SHAKEN is published by AT&T, Verizon, T-Mobile and US Cellular. In March, the FCC denied requests to extend the moratoriums from Verizon and US Cellular, saying that Applicants fail to meet the 'unfair difficulty' criterion. Verizon's lawsuit was limited to a small portion of its fibers. home phone network.

On the mobile side, "Verizon currently exchanges STIR/SHAKEN-enabled calls with wireless, which represents approximately 80% of the total wireless industry in the United States." "More than 135 million calls are exchanged daily between Verizon and carriers, and that number is growing rapidly." It is also published on VoIP telephony networks operated by Comcast, Charter, AT&T, Verizon, and others.

STIR/SHAKEN 'Finally' is widely used

Not for all robocall treatments. Its prevalence in landline networks is more fragmented than in mobile networks because it is very scattered due to persistent copper lines that do not support STIR/SHAKEN. In addition, some companies that encounter a large number of phone calls are not yet obligated to comply with these rules because they are exempted for carriers with 100,000 or fewer customers.

STIR (Secure Telephone Identity Identification) and SHAKEN (Signature) Confirm Information Based Management using toKEN protocols) Caller ID verification using public certificates based on public key cryptography is slowly attracting large US phone companies to use these The technology is an important turning point, as it ensures that STIR/SHAKEN is used by both sending and receiving carriers in many phone calls.

"Finally, the STIR/SHAKEN standards are a widely used fact in US telephone networks." “While there is no magic solution in the endless battle against fraudsters, STIR” SHAKEN Turbocharges many tools that are used to combat robocalls: from consumer applications and network blocking, to executive investigations and shutdowns. Used by international robocall campaigns. “The announcement

Congress ordered a STIR/SHAKEN order after voluntary compliance with FCC Chairman Ajit Pai’s program did not result in widespread approval. This deadline applies to major mobile and cement line providers, requiring them to “implement STIR/SHAKEN in the Internet Protocol (IP) parts of their networks.”

STIR/SHAKEN doesn't stop you from selling your phone. But it's useful because when this technology is used entirely by the carrier, it doesn't fake caller ID. This helps customers detect fraud and helps carriers improve blocking tools.Although STIR/SHAKEN is improving the quality of caller ID information, this does not mean the call is legal," the FCC said. Improved verification of the phone number called – or signals that it is not verified” also bans consumer-level services and before the call arrives helps the consumer. The FCC has offered limited exemptions to AT&T, Bandwidth Inc., Charter and Comcast and Cox and Ver izon Wireless and Vonage. But these exemptions were only available to carriers that meet the "basic performance standards". It confirmed that it expects to implement STIR/SHAKEN by June 30. These providers have to "provide a second certification after June 30, 2021, in fact, the purpose of the operation to which they previously committed." "

Fixed telephony, small carriers excluded

Due to technology limitations, the June 30th requirement did not apply to legacy networks. TDM-based networks are used with copper fixed lines. The Federal Communications Commission (FCC) says its rules "require service providers to use older forms of network technology to either upgrade their networks to IP or to actively develop an ID authentication solution." Caller IDs that operate on non-IP networks "

"according to According to a ruling by the Federal Communications Commission in September 2020, “a significant number of TDM-based networks still “expect a significant number of calls outside the framework of STIR/SHAKEN authentication.” This requirement does not yet apply to small phone companies, where carriers have been granted Telecoms with 100,000 or fewer customers as of June 30, 2023, to comply. The FCC is seeking comment on a plan to set the June 30, 2022 deadline, as "evidence indicates that a subset of small voice providers appear to be making large numbers of calls to their common base." “They are making more and more calls. Increased percentage of illegal calls compared to larger service providers. "

Because many companies send unsolicited calls, the FCC allows all calls to be made. Block malicious upstream voice service providers that transmit illegal or unwanted calls “when these primary service providers have been notified but have taken no action to block those calls, to other providers.” Advertising

Call mitigation database The mechanism

The FCC also launched its Robocall Reduction database in April and needs voice providers “to dissuade the agency from its efforts to reduce robocalls, including implementing the STIR/SHAKEN case.” As the FCC explained in a commission announcement Federal Communications This week, non-compliant providers can block their calls:

Starting September 28, 2021, if the voice service provider's certificate does not appear in the database, the intermediate and voice service providers will be prevented from accepting the provider's traffic Service Live, To date, more than 1,500 audio service providers are registered in the database, more than 200 audio service providers have full STIR / SHAKEN performance license and hundreds more are licensed for partial performance - generally they have full implementation certifications on IP parts of their networks - Those who authenticate other than fully implementing STIR/SHAKEN should describe new steps being taken to ensure that they are not the source of the illegal automated communication.

Unfortunately, Robusto calls from abroad are still an intractable problem, and several US agencies have worked to solve this problem. Aside from small audio providers, who have complained that hundreds of millions of rogue bots from India's Tema centers are tied to US residents, the Federal Communications Commission has pressured US-based companies to act as "gateways" to foreign bots to ban them.

AT&T Network Slot

There is at least one STIR/SHAKEN slot in a large network. In December 2020, AT&T told the FCC that it "recently discovered that a small volume of calls enter the AT&T network via a bulk VoIP platform (AT&T VoIP Connect or "AVOICS") and terminate AT&T VoLTE customers. SHAKEN header information cannot and therefore cannot Verified.” The FCC later stated that “by accepting AT&T, it will not be able to fully implement STIR/SHAKEN on its wireless network by the June 30, 2021 deadline. It was.” AT&T told the FCC that AVOICS affects “about four percent of AT&T VoLTE traffic" and that "active network segments" are expected to reach half of the affected traffic by June 30. by STIR/SHAKEN.” On June 22, an AT&T press release reported. The carrier now “blocks or labels over 1 billion phone calls per month” and uses STIR/SHAKEN to improve blocking and labeling with “additional data for detection and accuracy.”
