[SR-Users] is_present_hf error on select

[Kyle Kurz]

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?

$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
