The SPCE only understands a header "Privacy: id", so you'd need to do
some extra matching to catch "user;id;critical". To do so, copy
/etc/ngcp-config/templates/etc/kamailio/proxy/proxy.cfg.tt2 to
/etc/ngcp-config/templates/etc/kamailio/proxy/proxy.cfg.customtt.tt2 and
modify the customtt file accordingly.

Search for the line:

is_present_hf("Privacy") && $hdr(Privacy) == "id"

and change it to something like this:

is_present_hf("Privacy") && $hdr(Privacy) =~ "(^|;)id(;|$)"

Not sure if the proxy recognizes this regex, so you might need to
experiment a bit with it, or just set it to

is_present_hf("Privacy") && $hdr(Privacy) == "user;id;critical"

if you're 100% certain that it will always look like this (which I
wouldn't).

Andreas
