1.� Terminology

� � A SIP server is defined in RFC 3261 [2].� This server MUST be an

� � outbound proxy server, as defined in [3].� In the context of this

� � document, a SIP server refers to the host the outbound SIP proxy

� � server is running on.

� � A SIP client is defined in RFC 3261 [2].� The client can be a user

� � agent client or the client portion of a proxy server.� In the context

� � of this document, a SIP client refers to the host the SIP client is

� � running on.
