Configuration Option Descriptions¶
ca_file¶
These certs are used to verify the chain of trust for the certificate retrieved from the X5U Identity header parameter. This file must have the root CA certificate, the certificate of the issuer of the X5U certificate, and any intermediate certificates between them.
See https://docs.asterisk.org/Deployment/STIR-SHAKEN/ for more information.
ca_path¶
These certs are used to verify the chain of trust for the certificate retrieved from the X5U Identity header parameter. This file must have the root CA certificate, the certificate of the issuer of the X5U certificate, and any intermediate certificates between them.
See https://docs.asterisk.org/Deployment/STIR-SHAKEN/ for more information.
For this option, the individual certificates must be placed in the directory specified and hashed using the 'openssl rehash' command.
See https://docs.asterisk.org/Deployment/STIR-SHAKEN/ for more information.
crl_file¶
If you with to check if the certificate in the X5U Identity header parameter has been revoked, you'll need the certificate revocation list generated by the issuer.
See https://docs.asterisk.org/Deployment/STIR-SHAKEN/ for more information.
crl_path¶
If you with to check if the certificate in the X5U Identity header parameter has been revoked, you'll need the certificate revocation list generated by the issuer.
See https://docs.asterisk.org/Deployment/STIR-SHAKEN/ for more information.
For this option, the individual CRLs must be placed in the directory specified and hashed using the 'openssl rehash' command.
See https://docs.asterisk.org/Deployment/STIR-SHAKEN/ for more information.
failure_action¶
-
continue- If set to 'continue', continue and let the dialplan decide what action to take. -
reject_request- If set to 'reject_request', reject the incoming request with response codes defined in RFC8224. -
continue_return_reason- If set to 'return_reason', continue to the dialplan but add a 'Reason' header to the sender in the next provisional response.
untrusted_cert_file¶
If you with to check if the certificate in the X5U Identity header parameter has been revoked, you'll need the certificate revocation list generated by the issuer. Unfortunately, sometimes the CRLs are signed by a different CA than the certificate being verified. In this case, you may need to provide the untrusted certificate to verify the CRL.
See https://docs.asterisk.org/Deployment/STIR-SHAKEN/ for more information.
untrusted_cert_path¶
If you with to check if the certificate in the X5U Identity header parameter has been revoked, you'll need the certificate revocation list generated by the issuer. Unfortunately, sometimes the CRLs are signed by a different CA than the certificate being verified. In this case, you may need to provide the untrusted certificate to verify the CRL.
