Re: [sr-dev] [kamailio/kamailio] Branch ordering behavior changed between v5.3 and v5.4 (#2449)

Hi,

Is it possible that the branches are handled differently when they're added by append_branch()?

    append_branch("sip:1001@gateway1.carrierB.com;transport=tcp", "0.3");
    append_branch("sip:1001@gateway2.carrierB.com;transport=tcp", "0.2");
    append_branch("sip:1001@gateway3.carrierB.com;transport=tcp", "0.7");
    append_branch("sip:1001@gateway4.carrierB.com;transport=tcp", "0.5");
    append_branch("sip:1001@gateway5.carrierB.com;transport=tcp", "0.6");
    xlog ("=== $(branch(uri)[0]), $(branch(q)[0])\n");
    xlog ("=== $(branch(uri)[1]), $(branch(q)[1])\n");
    xlog ("=== $(branch(uri)[2]), $(branch(q)[2])\n");
    xlog ("=== $(branch(uri)[3]), $(branch(q)[3])\n");
    xlog ("=== $(branch(uri)[4]), $(branch(q)[4])\n");
    t_load_contacts();
    while (t_next_contacts()) {
        xlog ("==== $ru\n");
    }

https://www.kamailio.org/docs/modules/devel/modules/tm.html#tm.f.t_load_cont...

Function t_load_contacts() **removes all branches** from the current destination set and stores them into the XAVP whose name is configured with the parameter contacts_avp

It doesn't matter how you're adding branches before. t_load_contacts() will remove them.
