Enable Inbound Call Verification for a Trunk

This topic describes how to enable inbound call verification for a trunk. Once enabled, the system will verify all inbound calls routed through the trunk, and reject calls based on pre-defined rejection criteria.

Prerequisites

You have configured inbound call verification policy.
Ensure that the trunk is a Register Trunk or Peer Trunk.
Note: STIR/SHAKEN is not supported on Account Trunk.

Procedure

Log in to NovoOne Platform portal, go to SIP Trunks > SIP Trunks.
Click beside the desired trunk.
In the Advanced tab, scroll down to the STIR/SHAKEN section.
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: Sign outbound calls and verify inbound calls routed through the trunk.
Click Save.

Result

The system 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 within the associated tenant portal.
- The SHAKEN attestation level and reject reason of each inbound call are recorded in the Call Detailed Records (CDR) of the tenant (Path: CDR & Recordings > CDR > ).
- When an inbound call is rejected, an Inbound Call Rejected due to STIR/SHAKEN Verification Failure event notification is triggered in the tenant.
