Hello,
I have some trouble reading the headers.
Asterisk 16

in my dial plan I have these:

...
exten => _X,n,NoOp(Number of STIR/SHAKEN identities: ${STIR_SHAKEN(count)})
exten => _X,n,NoOp(First STIR/SHAKEN identity: ${STIR_SHAKEN(0,identity)})
exten => _X,n,NoOp(First STIR/SHAKEN attestation: ${STIR_SHAKEN(0,attestation)})
...


and I do get this:
-- Executing [********@incoming:2] NoOp("PJSIP/flowroute-0000003c", "Number of STIR/SHAKEN identities: 1") in new stack
    -- Executing [**********@incoming:3] NoOp("PJSIP/flowroute-0000003c", "First STIR/SHAKEN identity: +1********") in new stack
    -- Executing [**********@incoming:4] NoOp("PJSIP/flowroute-0000003c", "First STIR/SHAKEN attestation: ") in new stack


Why do I not see the attestation?
Also I do not see any validation. What am I missing here?
