[OpenSIPS-Users] Redirect & LCR

[Jeff Pyle]

It works quite well.  Here is my config chunk:

route[3] { # 302 Redirect for inbound traffic
if (!is_gflag("1")) { # Secondary server
$var(rU) = $rU;
$ru = "sip:" + $var(rU) + "@10.9.8.2:5060";
$ru_q = 400;
setflag(1);
}

if (!is_gflag("0")) { # Primary server
if (isflagset(1)) append_branch();
$ru = "sip:" + $var(rU) + "@10.9.8.1:5060";
$ru_q = 500;
setflag(1);
}

if (isflagset(1)) { # Send 302 if at least one set
sl_send_reply("302", "Inbound Redirect");
} else { # or 503 if none set
sl_send_reply("503", "Service Unavailable");
}

exit;
}



In the future this will become more sophisticated with db/cache lookups,
etc.  For now gflags provides enough control to toggle out a proxy from the
302 reply if necessary.
