Even in networks carrying large volumes of wholesale VoIP minutes and subscriber calls, BrixCall enables VoIP administrators to monitor the overall health of their service via an at-a-glance dashboard. The BrixCall dashboard presents critical information about the current state of the service, including all performance threshold violations, call disposition, average Mean Opinion Score (MOS), peak call volume and bandwidth utilization, answer seizure and network efficiency ratios, and call duration information.

For finer-grained visibility, a host of configurable Live Call Reports are accessible from the dashboard home page and can be customized for time period and filtered by protocol, codec, monitoring location, Diffserv codepoint, call duration, VLAN tag, and more.

The Call Activity View presents detailed information including source and destination numbers, MOS, duration, bandwidth, and performance metrics for individual calls or aggregated across multiple calls.

BrixCall features the unique Brix Tri-Q Analysis, and graphically displays the impact of each of the elements that contribute to a user's satisfaction with a call — signaling quality, delivery quality, and call quality.

Signaling quality measures the call's setup performance, such as protocol messages, post-dial delay, authentication registration times, hold time, and termination delay. Delivery quality measures the underlying network transport performance including delay, packet loss, audio loss, and jitter. Call quality reflects overall call experience in the form of a MOS. BrixCall relies on the ITU G.107 E-model algorithm to calculate and report listening and conversational MOS and R-factor measurements.

Leveraging the capability of the BrixWorx central-site software engine, BrixCall administrators establish and monitor performance thresholds to proactively alert operational staff of call quality degradations, outages, or abnormal calling patterns. Thresholds can be standardized network-wide or customized for individual locations, depending on business requirements.

To proactively avoid service outages and degradations and achieve visibility into individual call performance across production VoIP networks, administrators must employ a strategy that consists of both active testing of the network and VoIP infrastructure, together with monitoring the quality of actual live customer calls.

The addition of the BrixCall correlation application enables administrators to seamlessly configure, analyze, and monitor the right mix of active testing and live call monitoring for their environments, all from the Web-based BrixWorx Operations Center.
