Telchemy Software Embedded in Pivetal’s New VoIP Speech Quality Monitors

December 6, 2004


telchemyPivetal will provide real-time VoIP-specific monitoring of user-perceived quality, thanks to Telchemy’s call quality analysis software.

Telchemy, Inc and Pivetal, Ltd announced today that Pivetal has embedded Telchemy’s VQmon/SA Stream Analysis call quality algorithms in Pivetal’s new QspeeQ family of VoIP Speech Quality Monitoring products, allowing Pivetal customers to assesses user-perceived VoIP quality in real time.

This new VoIP-specific capability further enhances the ability of Pivetal’s Cortex Service Assurance Suite to identify and fix network issues before they impact on service quality levels. This meets the needs of service providers, large and small, to monitor and enforce SLAs (Service Level Agreements) at the customer premise, as they begin rolling out real-time multimedia services such as VoIP.

Traditional call quality management systems have not so far provided the diagnostic tools needed to support the SLAs for new IP-based services, generating a demand for more sophisticated capabilities.

Telchemy’s VQmon provides real-time analysis of VoIP calls, generating 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 standards-based call quality monitoring software that supports the IETF RFC 3611 (RTCP XR) Protocol and the new QoS reporting protocols for ITU’s H.323, H.248 and G.799.1 standards.

Telchemy releases new VQMON/EP Release 2.1

VQmon/EP 2.1 Software Supports RFC3611 and QoS Reporting Requirements for G.799.1, H.323 and Megaco

SUWANEE, Georgia –June 7, 2004 – Telchemy (R) Incorporated, the global leader in VoIP performance management technology, today announced VQmon (R) /EP (End Point) Release 2.1 which provides integrated call quality monitoring and reporting for IP phones and media/trunking gateways. As more service providers and enterprises deploy VoIP, real-time performance monitoring becomes critical for reliable service operation. VQmon/EP 2.1 supports RFC3611 (RTCP XR) and QoS reporting requirements for IP phones and gateways — including the new G.799.1 trunking gateway standard.

Other key features of VQmon/EP Release 2.1 include:

• full extended E model (G.107 with TS 101 329-5 Annex E)

• real-time alert generation

• support for jitter buffers that discard fractional packets

• dynamic configuration of VQmon-based probes, including Telchemy’s new SQprobe (TM).

VQmon/EP 2.1 will be available July 31, 2004.

About VQmon/EP

A member of Telchemy’s VQmon family of software performance management products, VQmon/EP is used in IP endpoints, such as IP phones and media/trunking gateways, to monitor the quality of live calls and provide the call quality and diagnostic metrics needed to support management protocols and problem diagnosis. VQmon/EP supports real-time thresholding, generates and interprets RTCP XR payloads and provides the metrics for signaling-based QoS reports. The software is fast, efficient, scalable and highly portable which minimizes costly implementation time and reduces time to market. VQmon is fully compatible with VQmon(R) /SA (Stream Analysis) and a wide range of VoIP test equipment.
