Of course you are correct in general. When you add a new sipx server and you are configuring reconfiguring DNS to enter the new server as an SRV record. You will also be reconfiguring sipx. The two are not done independently of each other. You will be expected to restart the services. I believe sipxconfig will expect you to do that.
