SafeCall configuration

To implement STIR/SHAKEN, perform the following steps:

1. Register with the Policy Administrator on the Service Provider page to receive a Service Provider Code Token.
2. Set up an account with an approved certification authority, such as TransNexus, to obtain a digital certificate necessary to sign the calls with a digital signature.

1. Configure/update the service policy that is assigned to vendor connections, including the internal vendor connection:
   • Open the Service catalog > Service policy > Attributes > SIP headers tab.
   • Select the checkbox for Stir signature required option and turn on the toggle.
     
2. Configure the Override identity feature for outgoing calls:
   • Open the Customer > Services > Voice calls > Outgoing calls tab.
   • Turn on the Override identity toggle.
   • Configure Identity and Display Number fields if needed.
   • Set the Attestation level that specifies the level of your confidence in the customer and the phone numbers they use. Select one of the following options:
     • Full attestation. The service provider authenticates the user making the call and confirms they are authorized to use the phone number. For example, the authenticated user makes a call using the phone number allocated by the service provider. Note that the verification sign [V] is only displayed for users if the caller has the full attestation level.
     • Partial attestation. The service provider authenticates the customer making the call but cannot confirm that the calling party is authorized to use the phone number. For example, a call is initiated by your PBX customer from a non-authorized number.
     • Gateway attestation. The service provider indicates that they let the call enter on their network, but they cannot verify the call originator. For example, a call is received from an international gateway or a wholesale partner.
       

You can override the outgoing call configuration, including the Attestation level, for a specific account.

1. Open the Product > Services > Voice calls > Incoming calls tab.
2. Turn on the Perform caller verification toggle.
3. Set the Display name indicator as Caller name and SIP headers.
   

Alternatively, you can configure the incoming call verification for each account separately.

If an incoming call passes the verification, the user sees the [V] sign before the phone number, meaning that they can trust the calling number they see on their phone.
