A Call Placement Service (CPS) is used to receive PASSporT Identity tokens transported with Out-of-Band SHAKEN. The CPS makes these tokens available to the terminating service provider’s verification service (STI-VS) to verify call authentication information using standard STIR/SHAKEN processes.

Out-of-Band SHAKEN standards are under discussion within the ATIS IP-NNI Task Force.

In this webinar, TransNexus will describe how to build a distributed, redundant, secure CPS using open source tools. The presentation, accompanying documentation, and open source code will provide attendees with sufficient detail to build their own CPS.
