Pivetal Integrates Telchemy's VQmon VoIP Fault and Performance Management Software into New VQM Probes.

SUWANEE, Ga. -- Collaboration Provides QoS Monitoring For Telecom Carriers, Service Providers and Leading-Edge Broadband Network Service Providers

Telchemy(R) Incorporated, the global leader in real-time VoIP Performance Management software, and Pivetal Limited, world-class provider of artificial intelligence-based network management systems, today announced that Pivetal has embedded Telchemy's VQmon/SA(R) (Stream Analysis) call quality analysis algorithms in their new QspeeQ(TM) family of VoIP Speech Quality Monitoring products. By adding Telchemy's VQmon technology, Pivetal will provide VoIP-specific monitoring to its customers that assesses user-perceived quality in real time. This new VoIP specific capability further enables Pivetal's Cortex(TM) Service Assurance Suite to identify and fix network issues before they impact on service quality levels.

"Call quality and Performance Management are critical success factors in the deployment of real-time multimedia services by both domestic and international VoIP service providers," said George Hamilton, Senior Research Analyst, Enterprise Computing and Networking, Yankee Group. "With Telchemy's sophisticated standards-based technology embedded in their new probes, Pivetal is providing service providers with a robust, flexible, cost effective distributed network monitor."

Specifically, Pivetal will feature VQmon/SA call quality monitoring and analysis technology in the following products:

--QspeeQ/CP - This customer premise probe monitors all voice call streams and deduces from these speech quality metrics for SLA supervision purposes. It also captures speech quality metrics reported by VQM enabled gateways and endpoints in the subnet it monitors and forwards this (along with its own VQM metrics) to a central QspeeQ/GW probe.

--QspeeQ/GW - This sophisticated stand alone probe also hosts an instance of QspeeQ whose function is to monitor and calculate the speech quality of all off-net calls at the point of egress from the VoIP 'cloud' adjacent to the media gateway. It produces an overall call speech quality record (CQR) by combining the VQM metrics of both 'ends' of each call. This raw CQR can then be used to generate alerts, aggregated into higher-level management information, "historised," etc.

"As service providers, large and small, begin rolling out real-time multimedia services such as VoIP, the need to monitor and enforce SLAs (Service Level Agreements) at the customer premise becomes critical," explained Louis Meyer, CEO and Founder of Pivetal. "Our customers realize that traditional call quality management systems don't provide the diagnostic tools needed to support the SLAs for new IP-based services like VoIP. Hence, they are specifically requesting advanced monitoring and diagnostic tools that contain sophisticated technologies like Telchemy's VQmon/SA feeding vital call quality metrics into our Cortex fault and performance management products."

VQmon provides fast, accurate, real-time analysis of VoIP calls, generating call quality metrics, including: listening and conversational quality scores and detailed diagnostic information on the severity and distribution of packet loss, discards and jitter. VQmon is the first standards-based call quality monitoring software to support the Internet Engineering Task Force (IETF) RFC 3611 (RTCP XR) Protocol and the new QoS reporting protocols for International Telecommunications Union's H.323, H.248 and G.799.1 standards.

"Pivetal continues to break new ground in the area of QoS and service level assurance worldwide," said Alan Clark, President and CEO of Telchemy, Incorporated. "By embedding VQmon into its QspeeQ line of probes, Pivetal is providing their customers with proven, standards based call quality and performance management for tomorrow's multi-service, multi-media marketplace."
