Telnyx has been fully SHAKEN/STIR compliant since June 30th, 2021. We have been attesting to all calls originating on the Telnyx network, and passing the identity header on to the recipient for inbound calls that have been signed by the originating provider. However, customers have not able to view the attestations.
As of today, customers will have visibility into attestations via the ability to check SHAKEN/STIR call compliance by consulting Call Detail Records (CDRs) on Reporting Detail Reports.
Telnyx CDRs will now present an additional field, “Stir Shaken,” that can have the following values:
For inbound calls Telnyx will verify the content of the Identity header and for outbound calls Telnyx will authenticate and generate an Identity header. The results for both authentication and verification will be added to the CDR that can be retrieved by Telnyx users through Mission Control Portal.
For inbound calls (calls from the PSTN to Telnyx customers), Caller ID SHAKEN/STIR results in the CDR are mapped in the following way:
| SHAKEN/STIR Identity | Attestation | Validation | CDR “Stir Shaken” Value | |||
| Provided | A | Passed | A | |||
| Provided | B | Passed | B | |||
| Provided | C | Passed | C | |||
| Provided | - | Not Passed | Invalid | |||
| Not Provided | - | - | Unavailable |
For outbound calls (calls from Telnyx to the PSTN), Caller ID SHAKEN/STIR results in the CDR are mapped in the following way:
| SHAKEN/STIR Identity | Attestation | Validation | CDR “Stir Shaken” Value | |||
| Provided | A | Passed | A | |||
| Provided | B | Passed | B | |||
| Provided | C | Passed | C |
This capability is only applicable to US domestic calls (calls from +1 prefix to +1 prefix)
For on-net calls, please ensure you register with your credentials connection via TCP or for IP/FQDN connection please specify TCP as the inbound transport protocol. This will help to prevent packet fragmentation and call completion issues.
