Clarification in Stir/Shaken Outgoing Call Flow section

[oza4h07]

In Outgoing Call Flow section, point 7 from [1], you can read, that “If there’s no “tn” object matching the caller-id, skip attestation and continue the call.” Can this matching be further clarified or detailed using an example, such as bellow ?

"Example: For instance, if CALLERID(num) is valued to 123456789012 and “stir_shaken show tns” displays a line “TN: 123456789012” , then there is match.

Alternatively, if CALLERID(num) is valued to +123456789012 (+E164 notation) and “stir_shaken show tns” still displays a line “TN: 123456789012” , then there is NO match."

IMHO, one interesting addition could describe what happens in case of contradicting information in P-Asserted-Identity and From headers, in case P-Asserted-Identity is customized in dialplan. Alternatively, a warning against customizing P-Asserted-Identity in dialplan may makes sense.

Thanks for the comments. I'll clarify the documentation.
