[OpenSIPS-Users] DB Aliases and branches

[Bogdan-Andrei Iancu]

Hi Doug,

A simple solution will be to move all the branches into some AVPs that 
you can consume (one by one) in a failure route.

to move branches try:
    $var(i) = -1;
    while ( $(branch(uri)[$var(i)])!=NULL) {
        $avp(i:100) = $(branch(uri)[$var(i)]);
        $var(i) = $var(i) -1;
    }

Note that I'm iterating through the branches from end to head, as the 
AVPs work as a stack (first inserted value will be the last).

Regards,
Bogdan
