RADVISION SIP Server Platform - B2BUA Application Framework (B2BAF)

RADVISION’s B2BUA Application Framework (B2BAF) module is a unique and highly flexible Application and Service Creation Framework for the rapid development of high performance B2BUA applications and services. Part of the RADVISION SIP Server Platform, the B2BAF is an ideal SIP application server and network equipment server framework.

The B2BUA Application Framework unique architecture enables developing SIP applications by combining customizable modular application building blocks. These modular application building blocks are effectively large chunks of functionality that can be strung together to form ad hoc applications rapidly.

RADVISION B2BUA Application Framework Benefits:

Significantly reduce time to market developing proprietary B2BUA applications by using off-the-shelf highly customizable application and service building blocks
Add advanced services easily to retain competitive advantage and evolve service offering to meet growing customer demands flexibly
Focus on the business logic by using the high-level business logic functionality offered by the B2BAF application and service building blocks

B2BAF Service
	A large “chunk of functionality” that can be strung together to form ad hoc applications. B2BAF services serve as application building blocks.
B2BAF Service Library
	A collection of services available for developing ad hoc applications.
B2BAF Core Runtime Engine
	The core runtime engine of the B2BAF, driving the B2B application, by dispatching services and communicating messages between services and the application.
