It doesn't add anything significant. I suppose it protects against weird icmp attacks but you'll have the same issues with all the rtp ports that you need to have open but may or may not have an open port on the other side. If you have something listening on those ports but don't want outside access to them, thats a different story. Mike On Jul 29, 2013, at 6:33 AM, Jim Lynch <jim@k4gvo.com> wrote:

You only need the sip ports your actually using, not all of 5060-5090 (but it wouldn't make a difference as we are not listening on them if your not using them).
So you're saying it's safe to keep the sip ports open.
