VQmon/EP is small (630kbytes) and highly efficient (<500 instructions per second) VQmon/EP detects packet loss and jitter buffer discard events, extracts key information from DSP software and produces call quality scores and diagnostic data. VQmon/EP has been integrated with products from Audiocodes, Global IP Sound, and Texas Instruments. Other leading DSP software vendors work closely with Telchemy to ensure that integration of VQmon with CODEC and Jitter Buffer software is seamless.

Specifically designed for integration into VoIP endpoints such as media gateways, IP phones, traditional TDM gateways and hybrid IP/TDM systems, VQmon/EP monitors voice calls and produces call quality estimates that can be reported as MOS scores and R factors through the media path using RTCP XR (RFC 3611), end of call signaling or SNMP. VQmon/EP is small (630kbytes) and highly efficient (<500 instructions per second) VQmon/EP detects packet loss and jitter buffer discard events, extracts key information from DSP software and produces call quality scores and diagnostic data. VQmon/EP has been integrated with products from Audiocodes, Global IP Sound, and Texas Instruments. Other leading DSP software vendors work closely with Telchemy to ensure that integration of VQmon with CODEC and Jitter Buffer software is seamless. VQmon generates listening and conversational quality MOS scores and R factors and a wide range of diagnostic data, making these available through an API as raw metrics, RTCP XR and SIP QoS Report payloads. VQmon is based on the ITU E Model with many extensions to improve accuracy under time varying network conditions, wideband codec’s, and orthogonal impairments and signal related parameters.
