CALABASAS, Calif. -- Ixia, a leading supplier of IP test systems, today announced the next generation in residential and business VoIP testing. With its ultra-high performance, IxLoad™ Voice matches the capacity of modern media gateways with an unprecedented 1 million SIP- and RTP-based endpoints per chassis – five times the capacity of its nearest competing product. Ixia’s new Acceleron™-XP load module implements voice protocols with hardware to reach these major capacity milestones.

IxLoad tests VoIP network components, including IP-based PBXs, softswitches, call managers, session border controllers, and media gateways, using highly realistic scenarios involving multiple voice protocols, complex calling sequences, and triple-play mixes of voice, video and data traffic. IxLoad’s unique subscriber modeling emulates user communities that vary in service usage and timing. This approach yields performance results that accurately predict live-network capacity – allowing service providers to correctly provision their networks. Ixia supports all of the essential VoIP signaling and transmission protocols, including SIP, RTP, SCCP, MGCP, H.323, and H.248 – with complex call flows and Class 5 features.

After many years of isolated, small-scale consumer and business roll-outs, VoIP deployments have finally gone mainstream. Infonetics Research forecasts a 25% compound aggregate growth in residential and SOHO hosted VoIP subscribers through 2011, when they are expected to number over 187 million. To meet this growing demand, network equipment manufacturers must deliver VoIP devices that can handle more calls and a complex array of protocols and services. Both network equipment manufacturers and converged service providers of all sizes need to verify the performance and interoperability of new VoIP devices and networks, ensuring that they can handle complex, heavy VoIP traffic loads.

“VoIP protocols and technology may be well understood, but there are a host of potential problems when a high number of calls are mixed with large volumes of data and video traffic,” said Anupam Sahai, vice president of marketing at Ixia. “We developed our Acceleron-XP, VQM modules and IxLoad test application to emulate city-scale communities of real-world users – allowing our customers to discover and solve their device and network problems before their customers do.”
