The SIP Application Server (B2BUA) provides a scalable, reliable, and feature-rich environment for rapid service creation. Aricent's B2BUA Server is a framework that exposes a set of well-defined APIs to the application to develop various services, such as Prepaid, Nat Traversal, Call Queuing, Click-to-Dial, and Call Pick-Up. These APIs as well as their parameters are Open Service Architecture (OSA)-compliant. In addition, Aricent's B2BUA Framework also supports additional APIs to create innovative applications.
Salient Features
- RFC-compliant: RFC 3261-compliant B2BUA
- Scalability: Highly scalable feature distribution
- Availability: Reliable high availability support
- Comprehensive support: Support for multi-party,
multimedia call control
- Flexible: Provides the applications complete access
to SIP messages
- Multiple deployment options: Single node or multi
node deployment

Architectural Features
- High availability APIs to allow the applications
back up serialized critical data and reconstruct the
state based on critical data
- APIs to send SUBSCRIBE, NOTIFY, MESSAGE, and proprietary
SIP messages in order to facilitate development of
presence-based applications and chat applications
- APIs to move call-legs from one call to another
in order to facilitate development of applications,
such as Call Pick-Up
- In-built Load Monitor to protect against overload
conditions
- Event criteria filtering mechanisms
