SIP-SF Architecture

Aricent's award winning SIP Server Framework (SIP-SF) ("Internet Telephony" Product of the Year 2002 and "Communications Solutions" Product of the Year 2003) is an ideal platform for hosting SIP services. SIP-SF is a ready-to-deploy SIP Proxy, Registrar, Redirect, Presence and Location Server. Aricent's SIP-SF today provides several advanced features, including SIP Centrex (Hosted PBX) and Per-User Call Processing Language, all of which render tremendous value in using it as an underlying platform to build new services while significantly reducing time, risk, and cost to market. The SIP-SF is a ready-to-deploy platform with Virtual IP redundancy, SIP Load Balancing, SNMP Manageability, Congestion Control, Emergency Calling, and other real-life network requirements already addressed.

Targeted at OEMs, SIP-SF has been developed keeping in mind the flexibility and extensibility that OEMs so much need to be able to offer differentiated products to the market.

Aricent's SIP server is a dual play architecture, positioned as both Core Infrastructure and Application Development Framework.

SIP-SF Core Infrastructure Element	OSA Application Server

Aricent's SIP Server can be positioned both as the SIP core infrastructure element to build basic infrastructure needed in a SIP Network or using its B2BUA feature set, as well as an application infrastructure to build applications, such as Collaboration, CTI, and Gaming. The SIP-SF thus enables one to easily integrate multiple call models, be it BCSM-based or RFC 3261, and to use any one of them depending on the kind of service being executed. Further, the SIP-SF can be made to interact with an SCN using a regular BCSM-based model and at the same time, perform forking functionality of proxy using the regular 3261 UAC/UAS model.
