The last update to the dialog updates the key to expire in branch_expire
seconds (default 180), in topos_redis_storage.c tps_redis_end_dialog()
The timeout is set to
    /* dialog ended -- keep it for branch lifetime only */
    lval = (unsigned long)_tps_api.get_branch_expire();
    if(lval==0) {
        return 0;
    }

I'm confused why:
-the dialog ended at the start of the call
-the dialog timeout isn't set to the dialog_expire value but to the branch_expire value
