Enable Inbound Call Verification for a Shared Trunk

This topic describes how to enable inbound call verification feature for a shared trunk. Once enabled, the associated P-Series Cloud PBX will verify all inbound calls routed through the trunk, and reject calls based on the rejection criteria.

Requirements

Procedure

  1. Log in to Yeastar Central Management, go to Cloud PBX > Trunk Sharing > Shared Trunks.
  2. Click besides the desired shared trunk.

  3. In the Advanced tab, scroll down to the STIR/SHAKEN section.
  4. In the STIR/SHAKEN Mode drop-down list, select either of the following methods:

    • Inbound Verification: Verify all inbound calls routed through the trunk.
    • Signing & Verification: Both sign outbound calls and verify inbound calls routed through the trunk.
  5. Click Save.

Result

  • The associated PBX verifies all inbound calls routed through the trunk, and rejects calls based on the rejection criteria configured in inbound call verification policy.
  • The inbound call verification results can be checked on the associated PBX.
    • The SHAKEN attestation level and reject reason of each inbound call are recorded in the Call Detailed Records (CDR) (Path: Reports and Recordings > CDR).

    • When an inbound call is rejected, an event notification called Inbound Call Rejected due to STIR/SHAKEN Verification Failure will be triggered.
