Hi,
I’m wondering how to use subst_hf() properly.
I’m trying to debug a broken flow by manually rewriting the contact header from
Contact: sip:b73c6f29-0101-4802-afcd-efb63f1e6d8f@10.10.10.12:5090;transport=udp
to
Contact: sip:2018092417381900003@81.x.x.x
by using
$var(ctct) = "sip:2018092417381900003@81.x.x.x"; subst_hf("Contact", “/<.+>/$var(ctct)\r\n/", "a”);
but the result is
Contact: sip:2018092417381900003@81.x.x.x sip:b73c6f29-0101-4802-afcd-efb63f1e6d8f@10.10.10.12:5090;transport=udp
Testing the regex with an external tool appears to match all of the original header, so I’m wondering why subst_hf doesn’t appear to rewrite the entire header.
Is there something I’m doing wrong?
TIA,
Ben
