Hey Mark,

It is not nice, but you can do:

$var(tmp) = $rU;
$rU = $fU
do_routing();
$rU = $var(tmp);

Hi Bogdan, I will try to explain better.

In rule_attrs I have a customer identifier which is used by acc to add the identifier into the CDR database. This works fine for calls from PSTN which are routed to another SIP gateway but calls from that gateway routed to PSTN can come from multiple customers and there is no way to identify which. So I'd like to match the incoming $fU to the rule that would match $rU in the from PSTN scenario in order to retrieve the rule_attrs (the customer identifier) from that rule.

Does that make sense?

Many thanks and regards
Mark.

    Hi Mark,

    What kind of matching you want to do between $fU and the dr
    prefixes ? You want to do the same as what drouting() does with $rU ?

    Hi everyone

    I am looking for a way to compare $fU in INVITE to the matching
    drouting() prefix of another group and retrieve the rule_attrs
    from that rule.

    At the moment I am thinking I'll have to run a custom DB query so
    I have 2 questions:

    1. Is there a better way to do this?
    2. If not, what is the best way to run custom DB queries?

    I have been reading through the drouting() documentation but that
    hasn't helped.

    OpenSIPS 2.4.7

    Many thanks!
    Mark.
