Hello,
In [1], you can read in Outgoing Call Flow section, point 7, 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 ?
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.
