Session Experience Manager - Optimize Your Voice Quality
AudioCodes Session Experience Manager (SEM) is an intelligent analysis tool designed to monitor the quality of Voice over IP calls within the enterprise network and its connecting trunks to service providers. By leveraging SEM, IT managers and administrators of hosted and managed services get a detailed view of the quality of voice traffic, allowing them to quickly identify, fix and prevent issues that can affect the voice calling experience at the enterprise.
Guarantee effective utilization, smooth performance and delivery of
expected QoS and SLAs of your VoIP network and services.
Intelligent Analysis of Voice Experience
SEM collects real-time statistics for voice and fax call attempts and IP traffic from AudioCodes devices within the enterprise network locations.
SEM presents intuitive graphical dashboard screens of the network elements, links and their associated VoIP measurements, forming a complete picture of the organization’s current and historical VoIP quality.
SEM provides an in-depth analysis with zoom-in reach on specific network elements and links such as SIP or TDM trunks.
SEM monitoring probes are provided on AudioCodes’ devices such as Enterprise Session Border Controllers and Media Gateways.
SEM does not require any network changes or additional network probes.
SEM integrates with AudioCodes Element Management System (EMS), enabling convenient device configuration updates as a quick remedy to identified performance issues.
SEM Main Applications
Network Map | Network Table | Time Based Statistics | Calls Drill Down | Alarms and Reports
Network Map: View a graphical, real-time snapshot of your entire VoIP network’s quality, enabling you to identify quality issues promptly and perform effective triage. The Network Map displays all monitored devices, the connections between them, and their current quality status.
Network Table: View all devices and links between them in sorted lists with associated voice quality metrics, enabling accurate root cause analysis and rapid identification of sources of quality degradation. Side-panel dashboard displays network status summary, graphic visualization of call success ratio, voice quality and alarms.
Time Based Statistics: Use the time-based statistics graphs for average call success/fail rates, quality metrics, and VoIP network bandwidth utilization to rapidly identify and isolate momentary problems and perform smarter network capacity planning.
Call Drill Down: Filter and search call records simply and effectively. Calls can be filtered by called party, caller, time/date, fail or success status, call quality metrics, and call duration. Convenient drill down to the details of a given call, including quality rating, control and media information, trends and alarms. Call trends enable rapid analysis of the call performance over the entire call duration, including time-based views of MOS, jitter, packet loss, delay and echo.
Alarms and Reports: Real-time and historical alarms triggered upon occurrence of VoIP quality issues with user defined thresholds, combined with search, sort and filter capabilities. Flexible summary, trend and top users reports per device or link, including user choice of tracked parameters and viewing options, and a unique fax transmission quality analysis.
