Next Generation Performance Management Application

SQmediator® is a scalable, high performance application that provides a global view of quality and performance for every call in an Enterprise or service provider unified communications network. SQmediator is the first performance management application to support the new RFC 6035 collector function that allows IP phones and gateways to report end-to-end QoE through SIP.

SQmediator collects QoS/QoE reports— including SIP RTCP Summary Reports (RFC6035) and other reporting protocols—sent by VoIP endpoints such as IP phones and gateways, or by Telchemy's SQprobe and SQlive, at the end of each call or at periodic intervals throughout a call. Quality report data is correlated, analyzed, and displayed in an intuitive dashboard-style Web user interface or exported via an integrated Web service interface.

The SQmediator Dashboard features color-coded, interactive Flash-based charts that provide an immediate view of recent and historical call quality, volume, and problem or alert conditions that indicate quality degradation. Users can easily identify bad calls and drill down into detailed metrics and diagnostic information that help rapidly determine the root cause of quality problems.

Automatic Correlation of Data for Individual Calls

SQmediator creates a quality record for each call. If multiple reports are received—for example, separate reports from each endpoint of a call, or interval reports throughout a call—SQmediator correlates the various reports into a single coherent record.

Convenient Dashboard Interface with Real-time Interactive Charts

SQmediator's Web user interface provides a real-time dashboard layout that makes it easy to monitor call performance across the network, and to quickly identify potential problem conditions and view system alerts. Interactive charts are color-coded to provide an immediate visual indication of call quality and volume, and permit fast "drill-down" into detailed report data for selected groups of calls or individual calls.

Expert Diagnosis of Problem Conditions

For each monitored call, SQmediator provides Expert Diagnostics: a straightforward text diagnosis of quality and performance that helps to expedite problem resolution and can be easily understood even by less technically-experienced support staff. (See example at right.)

Real-time Quality Scores and Performance Metrics

SQmediator reports perceptual quality scores and a wide range of diagnostic data based on reports from VoIP endpoints. Key reported metrics include:

• Listening and Conversational Quality MOS scores (MOS-LQ, MOS-CQ)
• Listening and Conversational Quality R factors (R-LQ, R-CQ)
• Burst and Gap Call Quality Scores - R-Gap, R-Burst
• Narrowband and Wideband R and MOS Scores
• Modem and Fax Quality Metrics
• Burst and Gap Loss/Discard Statistics

Immediate Problem Notification with SNMP Traps and E-mail Alerts

SQmediator can generate both SNMP and e-mail alert notifications to notify network personnel of problem conditions. Email alert preferences can be configured by severity and on a per-user basis. Individual, summary, and bulk alerts are supported.
