About JVS B2BUA

JVS B2Bua is originally based on Sippy B2BUA is a RFC3261-compliant Session Initiation Protocol (SIP) Back-to-back user agent (B2BUA) server software.

The B2BUA is a SIP call controlling component. Unlike a SIP proxy server, which only maintains transaction state, the B2BUA maintains complete call state and participates in all call requests. For this reason it can perform number of functions that are not possible to implement using SIP proxy, such as for example accurate call accounting, pre-paid rating and billing, fail over call routing etc. Unlike PBX-type solutions such as Asterisk for example, the B2BUA doesn’t perform any media relaying or processing, therefore it doesn’t introduce any additional packet loss, delay or jitter into the media path.

Logically, it consists of two independent signaling SIP UA connected by the call control logic.

Features

  • 5,000-10,000 simultaneous sessions per server;
  • 150-200 call setups/tear-downs per second;
  • Realtime calls control and call data records (CDRs) generation;
  • Optional ability to use Sippy RTPproxy for media relaying;
  • Optional ability to perform Cisco-compatible RADIUS AAA (Authentication, Authorization and Accounting);
  • RFC3261 compliance;
  • RFC3326 support;
  • IPv6 support;
  • Seamless compatibility with majority of popular SIP software and hardware on the market today;
  • Robustness and Resilience;
  • Simple and clean, yet flexible, internal design making implementing new features and services easy;
  • B2BUA could be easily combined with other Open Source software, such as SIP Express Router to build complete softswitch solution.

History

The development of the software started at the late 2003 after negative experience with using Vovida B2BUA. It was designed with robustness and performance in mind and now being used by several hundreds ITSPs all around the globe. The software now is being actively developed and maintained by the Sippy Software, Inc.

Special Thanks for the Sippy Software Inc. team on their continues development and maintenance to Sippy b2bua , JVS R & D Team is also sharing fixes and new features developed by JVS Solutions Inc. with Sippy Software Inc. development team.
