Genesys IP Media eXchange Testing Reporthot!

11.09.2006

CT Labs was commissioned by Genesys to evaluate the call-handling performance of the IP Media eXchange (IPMX). The IPMX compo-nents were deployed on one, two, and three Windows-based servers, respectively, for each of the three tests described in this report. All VoIP calls were generated using an automation script running on the Empirix Hammer FX-IP platform, using the SIP protocol. In the first test, the IPMX was deployed on a single server. The results of this test reveal that a single high-performance server with 150 agents configured can effectively process in excess of 250 simultaneous callers at a rate of 8 calls/second, with half listening to music on hold, and the other half connected to agents.

Navigating the Complexities of IMS (Empirix)hot!

07.09.2006

IP Multimedia Subsystem (IMS) is moving the communications industry towards a new business model. No longer are proprietary solutions with long development cycles and network-centric applications the solution for the network equipment manufacturer or service provider community to enable feature-rich services. Traditionally, end user, network, testing/monitoring, and maintenance applications have been dictated by the access and network infrastructure equipment capabilities and feature sets. These applications have been integrated into the legacy equipment and the ability to customize has been extremely limited. However, these applications due to their proprietary and static nature and long development timeframes are very reliable and provide a high quality end user experience. This quality and reliability needs to be duplicated in the IMS environment and applied to real-time, next-generation applications but in a much quicker timeframe across diverse networks and devices.

Ingate Systems: SIP Trunking Benefits and Best Practices hot!

19.06.2007

SIP Trunking Benefits and Best Practices By Janne Magnusson, Vice President, Product Management Ingate® Systems A complete guide to SIP trunks, this whitepaper provides a comprehensive overview on the basics of SIP trunking, including a discussion of infrastructure needs and deployment issues and solutions. In-depth sections dedicated to interoperability, security and quality and reliability issues are also included. Editorials from ShoreTel, Level 3, Cbeyond/SIP Connect and Ingate provide a unique look at the perspectives from the IP-PBX, ITSP and other thought leader points-of-view. SIP trunks can lower telephony costs and deliver rapid return on investment (ROI). They also offer the opportunity for enhanced communications both within the enterprise and with vendors, customers and partners. While some see SIP as just voice, SIP trunking can also serve as the starting point for the entire breadth of realtime communications possible with the protocol, including Instant Messaging, presence applications, whiteboarding and application sharing. Adding their unique insights to the white paper are editorials by: - ShoreTel, Inc. – “Developing a Working Solution End-to-End” - Level 3 – “A Service Provider’s Perspective on SIP Trunking” - Ingate Systems – “Who Is Listening to My Calls?” - Cbeyond – “SIP Connect: An Industry Collaboration Success Story”
