[OpenSIPS-Users] Using dispatcher's ds_select_domain with a variable

[Jock McKechnie]

Good morning;

I've been fiddling with dispatcher and I would like to maintain several
dispatcher sets that get selected based on the $ru. The $ru would be parsed,
a dispatcher set placed in a variable, and then ds_select_domain() would be
called upon the variable... except ds_select_domain() doesn't appear to work
with being called using variables... or perhaps I'm doing something wrong.

The $ru would look something like this: "+12125551212 at dispatcher1001", which
I'm using the following directives to handle:

if ($ru =~ "dispatcher") {
    $var(beep) = $(ru{s.substr,27,4});

    xlog("L_INFO", "[$Tf] Found dispatcher, set: $var(beep)\n");

    if (!ds_select_domain("$var(beep)","4")) {
        t_reply("503", "Unable to location dispatcher set requested");
        return;
        }

    route(1);
    return;
    }

The $var(beep) is being parsed out correctly (The xlog() messages show as
such), but get the following:
ERROR:core:fixup_get_ivalue: no valid PV value found (error in scripts)
ERROR:dispatcher:w_ds_select_domain: no dst set value
ERROR:tm:w_t_reply: failed to send a t_reply to a message for which no
transaction-state has been established

I suspect the important one in the list above is the first, where the
get_ivalue is failing, but I'm not sure. I suspect if it can tell it's a
variable then I probably am doing something amiss, but I sure would
appreciate if some learned soul could tell me what I'm doing wrong.

My thanks;

 - Jock
