Right now
i'm doing a redirect server and i'm trying to sinalize the
redirection using a 3xx reply. In order to do that, according the RFC I
need to add a Contact and Diversion header. How do i do that ? i'm creating
the reply with send_reply() but i can't seem to find a way to add these
parameters to the reply.
append_to_reply() (from textops) is your friend here:
append_to_reply("Contact: <sip:duarte@sip.rocha.aq>\r\n");
Why would you do it this way? All you have to do is manipulate $ru (or
its parts) and
send_reply("302", "Redirect");
exit;
Though append_to_reply might be needed for the Diversion (unless the
diversion module is any help here
