ClearIP now supports Rich Call Data in STIR/SHAKEN

Relays information about calling party for display on supported handsets

ATLANTA, Georgia, August 15, 2019 — TransNexus today announced support for Rich Call Data in its ClearIP STIR/SHAKEN software. This enhancement enables calling parties to include rich data that can be presented to called parties. The additional information, along with STIR/SHAKEN verification results, helps people decide whether to answer the call.

Illustrative examples

Rich Call Data display

Here’s a prototype display to illustrate the capabilities that Rich Caller Data can provide (note that this is a mock-up—the handset software is not currently available).

For comparison, below are four illustrative examples of a smartphone call answer screen showing the information provided by the standard display, CNAM, STIR/SHAKEN, and STIR/SHAKEN with CNAM (note: we used The Home Depot for illustrative purposes—we are not affiliated with The Home Depot.)

The Rich Call Data example is the most informative example, and therefore the most likely to encourage the called party to answer the call. For this reason, many enterprises are keen to take advantage of Rich Call Data.

Rich Call Data and STIR/SHAKEN

STIR/SHAKEN is a process where the originating service provider creates a PASSporT Identity token to authenticate and digitally sign caller ID information for an outbound call. The terminating service provider then verifies the caller ID information and signature so they can present verification status to the called party. This gives subscribers confidence in caller ID and encourages them to answer more verified calls.

Rich Call Data is an extension of this framework to enable the calling party to provide additional information about themselves to encourage the called party to answer their call. This information includes a display name and other optional information:

  • URL of an image file, which might present company icon and/or a photo of the caller
  • Web page, which might present information about the company
  • Either a jCard or the URL of a jCard posted on a website. This is a JSON object that can optionally provide many fields of information about the caller, such as:
    • Name
    • Address
    • Email
    • Additional telephone numbers
    • Birthday

Although the standards accommodate many fields of information, it is expected that calling parties, especially enterprises, will only use a few fields of information. The idea is to provide enough information to encourage the called party to answer the call.

Because rich call data is included in the PASSporT Identity token, it is part of the content used to digitally sign the token.

Rich Call Data is presented to the called party using software on their handset provided by the manufacturer or as an application that integrates with the handset’s telephone calling interface.
