Telchemy Inc. of Suwanee, GA, a voice and video over IP monitoring company, announced on Tuesday that it has licensed more than 2 million units of its VQmon VoIP performance management software. The company was also happy to report that license revenues for the software alone have more than doubled for this year's first three quarters when compared to the same period last year.
According to the company's release, VoIP product manufacturers and test equipment vendors have integrated VQmon into over 50 different product lines comprised of "a wide range of probes, analyzers, IP phones, residential and media gateways, routers and session/border controllers."
VQmon allows service providers and enterprise network managers to manage voice and video services, monitor service quality and service level agreements and diagnose problems affecting Quality of Service (QoS). The software is able to detect, monitor and resolve call quality and network related problems for networked multi-media services, including voice and video over IP, IP Centrex, 3G Cellular, Voice over WLAN (VoWLAN), and streaming audio/video.
VQmon provides listening and conversational call quality metrics in both R factor and MOS formats as well as detailed diagnostic info, allowing network managers to identify specific problems and measure their severity. The software also supports the new VoIP management protocols, providing the l metrics for the International Engineering Task Force (IETF) RFC 3611 (RTCP XR) media path reporting protocol and QoS reporting protocols for SIP, H.323, MGCP, Megaco and PacketCable.
"This is an important milestone for Telchemy, solidifying our position as one of the top worldwide suppliers of VoIP performance management technology," said Telchemy's president and CEO Alan Clark. "We look forward to continuing to break new ground in improving the quality of IP communications as it expands to video, 3G wireless, and voice over WiFi."
Telchemy made news back in September when it announced it integrated IPTV performance measurement technology into the VQmon/SA-VM video analysis software product. The VQmon/SA-VM is now embedded into set-top boxes, head-end systems, probes, analyzers and routers to monitor video over IP. The VQmon/SA-VM software agent monitors IP based video streams in real-time; measures the time distribution of lost and discarded packets using a multi-state statistical model; examines the type of video codec, bit rate and other factors; and uses a perceptual model to calculate a video transmission quality factor and an estimated VQS (MOS) opinion score. VQmon/SA-VM supports H.261, H.263, H.263+, H.264, MPEG1, MPEG2, MJPEG, MPEG4 and VC1 codecs over RTP/UDP and MPEG2 Transport/UDP protocols.
