Could someone point me in the right direction? Remote-Party-ID: "Cullen Jennings" <sip:+3123456789@1.1.1.1<mailto:sip%3A%2B3123456789@1.1.1.1>>;party=calling;privacy=off;screen=no. I’ve tried the following ways: 1) TEXTOPSX: $var(rpid_privacy_value) = @hf_value.remote_party_id.privacy; 2) Param Transformations: a. $(hdr(Remote-Party-ID){param.value,privacy}) b. $(re{param.value,privacy}) c. 4re{param.value,privacy} I can’t seem to extract the value of privacy from the RPID header.
