[OpenSIPS-Users] Store dialog value and fetch it

[Alexander Mustafin]

Hi, Răzvan!

I’m using topology_hiding() function - and loose_route() will always false.
match_dialog() in this route return TRUE and $DLG_status return 5 (dialog ended)

route[BYE] {
        xlog("L_DEBUG", "~~~~~ Enter in [BYE] section ~~~~~");
        xlog("---- DIALOG status [$DLG_status]"); #DEBUG

        $avp(radius_user) = $dlg_val("incoming_gate");
        $var(setup_time) = $dlg_val("start_time»);
}

Nov  9 09:23:54 ops /usr/sbin/opensips[26665]: ~~~~~ Enter in [BYE] section ~~~~~
Nov  9 09:23:54 ops /usr/sbin/opensips[26665]: ---- DIALOG status [5]

> Adding the match_dialog() call inside the BYE route only makes sense if the dialog was not mached yet. So in your case, it makes sense only if you call route(BYE); from a different part of script.
