STIR/SHAKEN#
DIDWW supports STIR/SHAKEN for outbound call termination via Outbound SIP Trunks. This includes default DIDWW attestation and an optional mode to relay a customer-generated SIP Identity header.
Default DIDWW Attestation#
By default, DIDWW applies STIR/SHAKEN attestation to outbound calls.
When a call is sent through a DIDWW outbound trunk:
DIDWW applies STIR/SHAKEN attestation to the call. Any SIP
Identityheader received from the customer is not preserved.The attestation level is assigned according to DIDWW policies and regulatory requirements.
No additional configuration or action is required from the customer.
Relay Customer Identity Header#
If the customer applies their own STIR/SHAKEN attestation, DIDWW can relay the SIP Identity header unchanged.
When a call is sent through a DIDWW outbound trunk:
The customer is responsible for generating and providing a valid SIP
Identityheader.DIDWW does not generate or modify the SIP
Identityheader.The original SIP
Identityheader provided by the customer is relayed unchanged.
To enable Identity header relay for your outbound trunks, contact sales@didww.com or customer.care@didww.com with a request to relay your identity header for outbound calls.
Note
This configuration is applied per trunk. It is recommended to use a separate trunk for STIR/SHAKEN traffic.
Activation is subject to technical and compliance review.
