Keep in mind that’s only on firewalls that are sip aware, many are not

On a stateful firewall you can also choose to only open the SIP ports. That'll depend on your SIP profile settings. 5060 at least, and perhaps 5080 too.
The firewall could look at the SDP, mark the RTP ports as related traffic and automatically open them for you too.
That can -only- work with normal SIP though - for obvious reasons if you're using TLS it won't be able to see the ports being used.

I'm running a simple switch. No phones are connected to the system from outside of my local network. The only wan connections I have are a couple of voip providers. None of my phones on the lan call outside of the lan. All they talk to is the switch.
I see a bunch of ports listed at http://wiki.freeswitch.org/wiki/Firewall but don't know if I need them all. I suspect I don't. I want to close up the firewall as much as I can.
Thanks, Jim.
