Case Studies

Consistent, high quality voice is the key to maintaining customer satisfaction. However, media quality in VoIP networks can suffer degradation from various factors such as faulty routers or the overloading of certain links. Chances are, in the past, a dissatisfied customer call was often your first indication that something was amiss. Today, MetaSwitch offers a superior alternative: MetaView Voice Quality Monitoring.™

Graph packet loss, jitter and round trip delay with MetaSphere Voice Quality Monitoring

MetaView Voice Quality Monitoring enables you to monitor the quality of calls traversing your VoIP network. This allows you to more easily diagnose the cause of voice quality issues and to remedy them quickly.

CONFIGURED THRESHOLDS

MetaView Voice Quality Monitoring may be used to debug a specific subscriber's problems or to help identify more general concerns within your VoIP network. Using configured thresholds, the system will alert you whenever a network problem arises.

STATISTICAL ANALYSIS

Qualified VoIP devices report statistics to the MetaSwitch Call Agent, based on the number and arrival time of real-time transfer protocol (RTP) packets. These reported statistics include:

  • Packet loss
  • Jitter
  • Round trip delay.

Voice Quality Monitoring statistics are viewable in any of the following ways:

  • In a new display panel in the MetaView Explorer (Client) that graphically illustrates the state of each link in the VoIP network
  • As aggregated statistics in the NMS statistics panel for a range of NMS objects
  • In the historical statistics database for a range of NMS objects.

METAVIEW GRAPHICAL DISPLAY

MetaView Voice Quality Monitoring utilizes a graphical user interface (GUI) panel in the MetaView Network Management System to represent your IP network. Configured network nodes are displayed with their interconnects represented by lines between each pair of nodes. These lines vary in thickness with call volume, and in color with whether the real-time values of any of the statistics are in breach of their configured thresholds.

INTEROPERABILITY

MetaSwitch supports receiving voice quality statistics from a variety of tested interoperable partner devices, including access, trunk and customer premise products. For a comprehensive list of interoperable partner products, contact MetaSwitch today.
