Configuration of Call Signing Endpoints
...
Endpoints will be configured as a list wherein users can create an unlimited number of endpoints, each with its own IP or FQDN.

Customer/Termination Trunk Group Configuration
We have added the ability for 46 Labs customers to sign calls on behalf of their customers if no token is included in the SIP Identity Header of the outbound call. We also provide the ability to block customer/termination attempts if the customer is supposed to sign their own calls but does not.

The STIR/SHAKEN "Endpoint” drop-down will allow the user to select a STIR/SHAKEN signing endpoint configured in the Call Signing Endpoints page. This field is required if STIR/SHAKEN Treatment = “Sign Unsigned Calls” and “Sign All Calls”.
