[Freeswitch-users] What ports are really necessary?

[Steven Ayre]

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.
