•Redirect Server

The SIP Application Module decides whether to proxy or redirect the call separately for each individual request. This decision is made based on subscriber service logic. If the decision is to redirect the request, a 302 Response message is returned with a list of alternate locations.

•Registration Server

The Registration Server performs registration on messages it receives from clients. The Registration Server stores information in the database.

•Location Server

The Location Server performs location lookup services using domain and user information stored in the database.

The SIP Application Module integrates the above logical servers, which are all defined in SIP Draft RFC 2543 (see note for specific reference), into a single server with the enhanced services provided by the Back-to-Back User Agent.

Network configuration

The SIP Application Module is configured with two network cards to allow for a network configuration that has a private side and a public side. Figure 2, “Example of network configuration,” shows the SIP Application Module and RTP Media Portal with public ports and ports that are internal to the private network. This network configuration provides security by placing all the components in a private network and exposing only the public signaling and ports to the public network.
