<div dir="ltr">Thanks guys, that worked. Follow-up question, I want to reroute the incoming packet to the sip URI in that header, but Kamailio is complaining about the use of a variable in t_relay_to_udp. Putting $var(b) in quotes just makes it try to use that literal string as the target host. Is there another way to accomplish this?<div><br></div><div>

            have any feedback on how to move forward? My code snippet is

            }</p>

    Apparently the syntax for accessing the header is not correct.
    @hf_value will look for a global variable with that name. Try with
    $hdr(). <br>
