devices. Information for each component is stored in .xml format to provide flexibility when describing the capabilities of the component.

Bearer Path Control

The SIP Application Module uses the RTP Media Portal to control media streams originating from and terminating to non-compliant SIP devices if they do not support media negotiations. The exception to this occurs when the originating and terminating parties are both the same device type. If both gateways are CSE 2000s, for example, the SIP Application Module does not use the RTP Media Portal.

Privacy Control service

The SIP Application Module supports Privacy Control based on draft-ietf-sip-privacy. This draft defines a mechanism that allows clients to supply a network server with their private user information while at the same time instructing the server not to pass that information outside the boundaries of the trusted network. The information is passed in a Remote-Party-ID header with the privacy indicator set to “full.” The SIP Application Module removes this header any time it forwards the message out over a public network interface.

Service package enforcement

A service package is made up of a user’s enabled network services, such as audio conferencing, and subscriber profile. The service provider defines the available service packages for the domain. The domain provisioner can then assign a specific service package to a subscriber.

Authentication services

The SIP Application Module performs user authentication when the server receives an incoming SIP request. The SIP Application Module supports the challenge-based Digest method for SIP Client-to-Proxy authentication. In Digest authentication, the SIP Application Module challenges a client when a SIP request is received. The SIP Client re-sends a SIP request with a valid password and user name attached. The request types to be authenticated are configurable.

Note: Only US ASCII is supported for user names.

The software performs authentication using the password of the subscriber originating the call. Only subscribers from a local domain actually have a password stored in the database to authenticate against. If a subscriber from a foreign domain (refer to the note below for definitions of these types of domains) places a call and authentication is required for a known foreign domain, the
