a SIP PROXY server is an intermediary that acts as a client for the
purpose of making requests on behalf of other SIP clients

a SIP REGISTRAR server accepts REGISTER requests from SIP clients and
makes that information available to others

Simple Traversal of UDP Through NATs (STUN) is a lightweight protocol that
allows applications to discover the presence and types of Network Address
Translators (NATs) and firewalls between them and the public Internet.

may I recommend google, blatant cut&paste occurred above

Proxy, SIP Registrar and a STUN server..
