Re: [SR-Users] is_present_hf error on select

Just an extra note for the records -- if you want to presenrve th request uri (which is $ru) in the forwarded message, you can set $du to the sip address of the hop where you want to relay the message.

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?

you could set $ru to the desired value, and the call t_relay().

$var(a) =$hdr(X-Digium-AppServer-Response-URI);
$var(b) =$(var(a){s.strip,4});
if (!t_relay_to_udp($var(b), "5060")) {
     sl_reply_error();
}

Thanks,
Kyle

    I'm trying to use the is_present_hf function to detect the
    presence of a user-defined header and getting the following
    errors in my Kamailio logs:

    2(12149) BUG: <core> [select.c:426]: run_select(): Select
    structure has not been resolved
    2(12149) ERROR: <core> [lvalue.c:416]: lval_assign():
    assignment failed at pos: (99,58-99,58)
    2(12149) ERROR: <script>: 

    A quick Google search yielded no results for why this could
    be happening. Originally, I had my code in route[REPLY], but
    noticed that was not one of the paths it was listed as
    available in the textops document, so I moved it to
    request_route, but got the same errors. Does anyone have any
    feedback on how to move forward? My code snippet is below:

    if (is_present_hf("X-Digium-AppServer-Response-URI")) {
         $var(a) = @hf_value.X_Digium_AppServer_Response_URI[1];
         xlog ("\n\nHERE RESPONSE URI $var(a)\n\n");
    }

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