STIR/SHAKEN Attributes

This table lists and describes the STIR/SHAKEN attributes used for RADIUS CDRs. The table includes attribute name, attribute description, attribute value, attribute value type, and the list of CDR message types for which the value is captured.

Attribute Name Attribute Description Attribute Value Attribute Value Type Messages
Acme-Stir-Signed-Request

This AVP indicates that the SBC has sent the signing request to the STI-AS and received a response. Values for this AVP mean:

  • 1— The SBC has signed the INVITE.
  • 0—The SBC has not signed the INVITE.
  • 2—Signing is not applicable for the INVITE.
 249, extension 11 String

STOP
Acme-Stir-Signed-Request-Exception-Id This AVP indicates that the SBC did not sign the INVITE because of a failure response from the STI-AS. It includes the ATIS defined service and policy exception id (e.g. SVC4000, SVC4001, POL4050). 249, extension 12 String

STOP
Acme-Stir-Verification-Request

This AVP indicates that the SBC has sent the verification request to the STI-VS and received a response. Values for this AVP mean:

  • 1— The SBC has verified the request.
  • 0—The SBC has not signed verified the request.
  • 2—Request verification is not applicable for the call.

Acme-Stir-Verification-Request-Exception-Id This AVP indicates that the SBC did not verify the request because of a failure response from the STI-VS. It includes the ATIS defined service and policy exception id (e.g. SVC4000, SVC4001, POL4050). 249, extension 14 String

Stir-VS-Verstat The SBC populates this AVP with the verstat values the SBC includes in the SIP INVITE following the Stir Shaken trigger. Potential values include TN-Validation-Passed, TN-Validation-Failed or No-TN-Validation 249, extension 15 String

Stir-VS-Reason The SBC populates this AVP with received reason information. 249, extension 16 String

Stir-TN-Used-For-AS-VS-Request This AVP contains the TN number captured by the SBC. TN selection uses the following priority:
  1. From the Tel PAI (if present)
  2. From the SIP PAI (if present, and Tel PAI is not present)
  3. From the “From” header if both Tel and SIP PAI are not present.

Stir-Div-Signed-Request Upon sending the DIV signing request to the STI-AS and receiving a 200 OK successful response from STIR-AS, the SBC enumerates the results in this AVP as follows:
  • 1—indicates DIV signing the INVITE
  • 0—indicates no DIV signing the INVITE
  • 2—indicates DIV signing is not applicable on the INVITE

Stir-Div-Verified-Request Upon sending the DIV verify request to the STI-AS and receiving a 200 OK successful response from STIR-VS, the SBC enumerates the results in this AVP as follows:

  • 0— indicates no DIV verification the INVITE

STIR/SHAKEN attributes are embedded under one extended Radius AVP.

  • type = 26 (vendor-specific)
  • length = ...
  • vendor-id = 9148 (acme)
  • vendor-type = 249 (extended-attributes)
  • vendor-length = ...
  • vendor-data = { x-attr-type (16-bit), x-attr-len (16-bit), x-attr-data (variable) }

An example of an AVP presenting the Acme-Stir-Signed-Request attribute indicating the SBC has signed the INVITE appears as follows: 

x-attr-type = 1 (Acme-Stir-Signed-Request) [1 byte]
x-attr-len = … [1 byte] 
x-attr-data = { version[1 byte], Acme-Stir-Signed-Request [depending on length]}

Additional STIR/SHAKEN Attributes

The table below specifies additional STIR/SHAKEN Oracle VSAs used for RADIUS verification. These VSAs are not extensions of Oracle attribute value 249.

Attribute Name Attribute Description Attribute Value Attribute Value Type Messages
Stir-VS-attest

Note:

The system populates this AVP when MAN compliance is enabled.
Populate the attest claim value from the STI-VS verification response within the JSON body for 3GPP deployments. If there is no attest claim in provided by the verification response, the system populates the Sti-VS-Attest field with empty values in all CDRs.

Values include A or B or C

Stir-Div-VS-Reason

Note:

The system populates this AVP when MAN compliance is enabled.
This object collects the reason value with the concatenation of the "reasoncode" and "reasontext" obtained from each Div Verify result of JSON body. The system collects the reasoncode and reasontext for Div Verify result, even if they are same.

Example: SIP ; cause=438 ;text="Identitysignaturepayloaddoesnotmatchthere-constructedone", ;cause=410 ;text="Application inactive""

Stir-Div-VS-Verstat

Note:

The system populates this AVP when MAN compliance is enabled.
This object collects the verstat values, enclosed in double quotes, for each verified div PASSporT. The system collects the value for each DIV verification result, even if they use the same code.

Examples include: "TN-Validation-Passed, TN-Validation-Failed, TN-Validation-Passed"
