UserNote: A new STIR/SHAKEN verification option "ignore_sip_date_header" has
been added that when set to true, will cause the verification process to
not consider a missing or invalid SIP "Date" header to be a failure. This
will make the IAT the sole "truth" for Date in the verification process.
The option can be set in the "verification" and "profile" sections of
stir_shaken.conf.
Also fixed a bug in the port match logic.
Resolves: #1251

Normally if a callerid TN isn't configured in stir_shaken.conf
|
|
no Identity header will be created. If this option is set,
|
|
however, an Identity header will be sent using this
|
|
attestation level. Since there's no TN object, you must
|
|
ensure that a private_key_file and public_cert_url are
|
|
configured in the attestation or profile objects for
|
|
this to work.

<para>This function will either return the number of STIR/SHAKEN identities, or return information on the specified identity.
|
|
To get the number of identities, just pass 'count' as the only parameter to the function. If you want to get information on a
|
|
specific STIR/SHAKEN identity, you can get the number of identities and then pass an index as the first parameter and one of
|
|
the values you would like to retrieve as the second parameter.
|
|
</para>
|
|
<example title="Get count and retrieve value">
|
|
same => n,NoOp(Number of STIR/SHAKEN identities: ${STIR_SHAKEN(count)})
|
|
same => n,NoOp(Identity ${STIR_SHAKEN(0, identity)} has attestation level ${STIR_SHAKEN(0, attestation)})
