SIP Server Framework is a powerful framework to build carrier-class reliable, scalable and feature-rich SIP applications. The Aricent SSF comprises two components:

• SIP Core Infrastructure Server
• SIP Application Server

SIP Server Framework serves as a base for Proxy as well as any other SIP-based server entity. SSF therefore, radically reduces time-to-market by providing a hassle-free infrastructure that:

• Implements all the core SIP functionality including state information automatically.
• Provides a carrier class framework that easily allows new components to be added in and out dynamically as well as statically.

The SIP-SF is a powerful yet flexible solution. It provides tested and standards compliant core SIP functionalities like Call State Control Function (CSCF), Proxy, Registrar, Redirect, B2BUA, and Location Server. More importantly the framework allows application developers to build upon these core functionalities and deliver niche applications. The framework isolates the application developer from all SIP specific protocol and behavioral details. The application developer can focus on what services to provide and the framework can take care of how. Aricent's carrier class, proven, interoperable solution thus helps the customers in reducing time and development costs. The Aricent solution, one of the most proven and mature products in the industry, handles live traffic for the largest Service Providers' network and for one of the largest Internet Telephony Service Provider (ITSP) Network in Japan.

Aricent has also introduced Centrex functionalities in its SIP-SF. The Centrex feature enables Equipment Manufacturers to build a hosted PBX solution in minimal time. The Aricent SIP Server Framework with Centrex functionality is a powerful framework with a sophisticated dial plan, a hunt group, privileged profiling and intranet/extranet calling.

SIP-SF Architecture

SIP's success stems from its simplicity of implementation, modularity of architecture and ability to deploy future-proof software components. The SIP-SF builds on these inherent advantages of the standard and provides a rich foundation of re-usable and extendable components required for implementing SIP servers. The SIP-SF's component based architecture allows for chaining of various components to obtain a desired functionality. More...
