If both phones and SIP proxy have public ip addresses you will only  send
signaling traffic to the proxy.

If some of the elements is behind nat, all traffic (both signaling and
media) will be sent to the proxy. Note that you will need some kind of RTP
proxy if you want that natted device is able to receive calls.
