[Kamailio-Users] [Solved] How to configure alias_db_lookup in config script

[JR Richardson]

Thanks for your quick replys.

Here is the syntax that is working for me:

route{
        # initial sanity checks -- messages with
        # max_forwards==0, or excessively long requests
        if (!mf_process_maxfwd_header("10")) {
                sl_send_reply("483","Too Many Hops");
                exit;
        };
        if (msg:len >=  2048 ) {
                sl_send_reply("513", "Message too big");
                exit;
        };

        if(alias_db_lookup("dbaliases")) {
        t_relay();

        }else{

        ds_select_dst("1", "4");
        t_on_failure("1");
        t_relay();
        }
}

failure_route[1] {
        ds_next_dst();
        forward();
        }
