Telchemy
Telchemy Incorporated is a privately held American corporation headquartered in Duluth, Georgia, United States, that designs and sells performance management software for Voice over IP, Videoconferencing and IPTV services.

History
Telchemy was founded in 1999 by Alan Clark who had previously worked for British Telecom, Dowty and Hayes. The company’s stated vision was to develop a distributed management architecture that performed end-to-end performance management using agent technology directly integrated into endpoints. Their first product, launched in early 2001, was VQmon, an embedded VoIP performance analysis agent that modeled the impact of time varying impairments [1] on perceptual quality, reporting MOS scores. VQmon was subsequently licensed by a large number of equipment manufacturers and is incorporated into test equipment, IP phones, media gateways, routers and chipsets. The company subsequently introduced a number of other products, including active test technology, agents for mobile handsets and performance management applications.

Standards contributions
Telchemy has made a number of contributions to international standards related to VoIP and IPTV performance management. Notably Telchemy initially proposed the use of RTCP XR for VoIP performance management (RFC3611), and SIP for VoIP performance reporting (RFC6035), in addition to the widely used MOS-LQ/MOS-CQ terminology (ITU-T P.800.1).
