STIR/SHAKEN

If you’re a voice service provider in the U.S. or Canada, you’re facing regulatory mandates and market pressure to prevent unwanted robocalls. This requires call authentication, and the accepted industry solution for that is STIR/SHAKEN.

“We still have a lot of TDM traffic. We started [ClearIP STIR/SHAKEN] with our Ribbon switchboard in release 14. We have zero cost [in it]. It works very well. We’re TRACED Act compliant today.”

— Dave Frigen, COO, Wabash Communications

“We’re running version 9.3 on our Metaswitch. We have a lot of TDM traffic. It was a simple process to get [ClearIP STIR/SHAKEN] up and running.”

— John Smith, COO, Blue Valley Tele-Communications

Out-of-Band STIR/SHAKEN call authentication

There are real-world issues that prevent successful transmission of the SHAKEN identity token across today’s telephone network. These issues limit the effectiveness of STIR/SHAKEN:

  1. Non-IP networks (e.g., TDM) cannot transmit the identity token.
  2. Some SIP network gear removes the identity token.
  3. Some SIP networks use UDP, which is prone to packet loss and fragmentation.

One solution to these problems would be for service providers to upgrade their networks. But such upgrades are expensive and time consuming, especially for larger, more complex networks.

There’s another way: Out-of-Band STIR/SHAKEN call authentication. With this approach, the identity token is sent separately, or out of band, across the internet. Everything else about the STIR/SHAKEN process remains the same.

TransNexus has developed Out-of-Band STIR/SHAKEN capability and includes it as an option in our STIR/SHAKEN solutions to help make STIR/SHAKEN benefits available to all subscribers and their providers. SHAKEN identity tokens can be sent in band, out of band, or both. This can be configured for subsets of calls, so you have considerable flexibility to send some tokens in band and others out of band.

“We are seeing some calls with a ‘[V]’ in front of the caller name [caller ID verified by ClearIP STIR/SHAKEN]. It surprised some of our customers. Once we explained what it means, that the caller ID was verified for that call, they were excited.”

— Rob Good, IT Director, Rhode Island Telephone

Out-of-Band STIR options

Rich Call Data

Rich Call Data is additional information about the caller sent in the SHAKEN token. The information is presented to the called parties, hopefully encouraging them to answer the calls.

We think this will be a game changer, especially for enterprises calling their customers. Imagine how helpful Rich Call Data would be in these situations:

  • A doctor’s office calls their patient to confirm an appointment.
  • A school clinic calls a parent to let them know their child is sick.
  • A delivery driver calls to confirm that someone is home to sign for the delivery.
  • A service contractor (e.g., plumber, electrician) calls to make sure someone is home to let the contractor in to do the work.

Rich Call Data provides a great opportunity for service providers:

  1. Service providers can offer Rich Call Data service to enterprise customers as a value-add.
  2. Because it’s built on STIR/SHAKEN, it’s secure. No spoofing.
  3. The enterprise customer provides the Rich Call Data, so it’s up-to-date and brand compliant.

TransNexus has included support for Rich Call Data in our STIR/SHAKEN solutions.

“Our customers can now see incoming calls verified with a special signature or certificate, letting them know they can trust what they see on their caller ID.”

— Joe White, CTO, Brightlink

Other robocall prevention measures

STIR/SHAKEN doesn’t prevent unwanted robocalls by itself—it prevents caller ID spoofing.

There are other call analytics techniques designed to prevent robocalls, but they are less effective when the calling number has been spoofed.

Effective robocall prevention requires both STIR/SHAKEN, to check for spoofing, and call analytics, which are much more effective when you know whether the number was spoofed.

These robocall prevention methods include:

TransNexus offers these services with our software products. They work great together.

“As soon as ClearIP services started, robocalls disappeared. Checking the email alerts from the CAPTCHA gateway, there were no false positives. Implementation was the easiest setup we’ve ever done. We received a very quick response to our inquiry, and setup was very fast.”

— Brian, Senior Voice Engineer, TelWare
