Hi Ben,
Could you post the xlog output and the resulting 302 ? Also be sure you
are using the latest 3.2 version - please post the `opensips -V` here.

I am using Opensips v.3.2 and I am attempting to replicate the 302
redirect outlined on the blog

<https://blog.opensips.org/2018/07/05/handling-sip-redirect-requests-in-realtime/>),
but am running into an odd issue.
I am using exec to execute an external program, which returns a URI as
a variable, which is then used to populate the $branch field, which is
then returned as the contact URI in the 302 response.
For reasons I cannot explain, even though the URI is correctly
formatted in the xlogs which I print off during the call request, when
the 302 message is received, the Contact URI is missing the end
‘>‘character. This means the server the 302 is being sent to doesn’t
ACK the message, as the contact URI is invalid.
If I specify the URI directly within OpenSIPs, then the contact header
is then formatted correctly.
Initially I thought the issue was related to the script returning the
variable (bash script), so I swapped to a Golang program, essentially
returning the same URI, but the same behaviour occurs with this as well.
The script is setup as follows…
if ( $si == '10.10.14.71' && is_method("INVITE") ) {
exec("/usr/local/bin/sbc-route", $tU, $var(out));
xlog("Value returned from Re-direct Script is
$var(out)");
$branch = $var(out);
xlog("Target is set as $branch");
send_reply(302, "Server Redirect");
exit;
}
Can anyone offer any ideas as to why this may be occurring?
