[SR-Users] best practice to dynamic route block based on $rd - Domain in R-URI

[Karsten Horsmann]

Hello List,


i solved this with an "simple" if statement.
For me surprising i tried this without success:

#!define NEWDOMAIN "some.domain.example"
$avp(newdomain) = NEWDOMAIN;

if ($avp(newdomain) == $rd) ...

and this dont match. Also i tried "" around all vars.
And copied into $avp and {s.tolower} all of them.
Nothing works.
avp_print() shows both avps as the same.

Anyway ---

My now working example is that one with avp_check.
Was hard to find the meaning of g/G and i/I in the module.
In the wiki i found an example description of tha avp_check flags.

if (allow_source_address(FLT_IVR)) {
        # OLD vs NEW - domain routing...
        $avp(newdomain) = NEWDOMAIN;
        $avp(pathinfo) = "outbound";
        # avp_check flags / avpops
        # g/G - use all values of the checked AVP (first parameter)
        # i/I - if strings are checked, do it case insensitive
        if ( avp_check("$rd", "eq/$avp(newdomain)/gi") ) {
            xlog("L_INFO", "go to new-gw\n");
            $avp(routing_target) = FLT_FSNODE;
        }
        else {
            xlog("L_INFO", "go to old-gw\n");
            $avp(routing_target) = FLT_OLDSBC;
        }
        xlog("L_INFO", "[$avp(pathinfo)] comes from IVR <$si> to <$ruri>
\n");
        route(DISPATCH);
        exit;
  }


Kind Regards
...
