Telchemy (News - Alert) Incorporated, a provider of VoIP and IP Video performance management technology, has introduced DVQattest Version 2.0, a powerful new active test system for unified communications.

Officials with Telchemy Incorporated said that DVQattest generates Voice over IP and Videoconferencing calls with SIP signaling, synthetic HTTP, POP3, SMTP, DNS and DHCP transactions and a range of IP network tests.

Company officials said that this advanced test product supports pre-deployment testing, SLA monitoring and troubleshooting for converged networks and services.

According to company officials, DVQattest Agents are compact but highly featured software applications that can be installed on a range of operating systems and hardware platforms, including Linux servers and appliances, Android (News - Alert) mobile phones and directly integrated into network equipment and CPE.

Tests can be run on-demand or scheduled to run indefinitely.

Moreover, agents can run multiple concurrent tests to other Agents or to IP phones, Web sites, Email sites and other network-based services. DVQattest Agents support complex networks with overlapping IP address spaces, VLANs and a range of SIP infrastructure configurations.

VoIP and Videoconferencing tests verify the performance of both SIP signaling and the media stream. Voice and Video quality is measured using Telchemy's market-leading VQmon technology, providing MOS scores and a wide range of diagnostic data. Voice over IP tests support configurable codec, packet size and jitter buffer configuration; Videoconferencing tests support configuration of codec, image size, GoP, frame rate, bit rate and smoothing.

Network tests include Agent-to-Agent tests that measure loss, jitter and available bandwidth in each direction, industry standard network tests and advanced route diagnostics. DHCP and DNS tests verify correct operation of vital network functions and HTTP/POP3/SMTP tests measure performance of key applications.

The DVQattest Controller provides an easy-to-use management application that supports test definition, remote DVQattest Agent management and test result collection and reporting.

Company officials said that DVQattest provides dependable, accurate and detailed performance metrics and has already been deployed in critical network applications.

DVQattest is available in a wide range of configurations, suitable for mid-large enterprise, hosted and cloud based services and tier one service providers.
