Even in times of Unified Communications the phone service is still the most important means of communication. Bad voice quality generally affects productivity when talking to coworkers, customers, and business partners. It is inacceptable for call centers where the primary business objective is talking to customers.

Voice quality issues encountered by enterprises and public agencies often have the following root causes:

  • Hidden issues within the CSP’s network
  • Insufficiently sized inter-site and access network links
  • Legacy networks in old sites, small branch offices and factories
  • Variety of problematic end-devices including fax machines, Wi-Fi phones, and softphones

 

The complexity of identifying responsibilities and root causes is further increased in the presence of managed services where one IP infrastructure is used to deliver services by different providers.

Qrystal enables enterprises and public agencies to:

  • Provide detailed documentation for the voice quality of each individual call
  • Alarm in case of problems
  • Quickly identify the root causes of problems
  • Pinpoint responsibilities in shared infrastructure and interconnection scenarios

These capabilities are critical to the successful management and operation of any enterprise VoIP service. In addition, unique Qrystal KPIs allow enterprises to verify and document the user experience and service performance, thus putting them on a par with their CSPs.

Customers appreciate the value-added services of NGN and IMS networks, yet their baseline expectation regarding call quality is predetermined by the traditional PSTN. In other words, CSPs can only gain a competitive edge, if they maintain excellent voice quality.

However, there are many potential reasons for service degradations. Impairments can originate in a CSP’s own network as well as in the networks of customers and interconnection partners. Isolating a problem source – particularly if it is not in your own network – can be a challenging task.

Qrystal is essential for keeping voice service quality under control. It enables CSPs to:

  • Monitor and document the speech quality of all actual VoIP calls
  • Optimize their networks
  • Offer service level agreements (SLA) for voice quality
  • Quickly identify the root causes of problems
  • Pinpoint responsibilities in shared infrastructure and interconnection scenarios

These capabilities are critical for guaranteeing a premium voice service whilst ensuring an efficient use of resources.

Monetizing MOS

Monetizing MOS

Voice service monitoring is often tactical in nature. Tools produce data that is used by operations to work on customer tickets and to generally ensure that the network and service performs as designed. Any Return of Invest (ROI) mainly comes from savings due to higher operational efficiency.

But why not use the existing data in other areas to increase revenue and reduce cost? Qrystal and Qrystal Intelligence are successfully used by operations and performance optimization teams. On top, information provided by Qrystal is also used by CSPs to increase brand value and revenue by providing customers with access to their own service quality data.

Here’s why transparency pays off:

  • Differentiation (few CSPs are confident about their data)
  • Potential to sell data as a service
  • Fewer tickets (if data proves that problems originate in customer network)
  • Potential for selling troubleshooting services to customers
  • Customers love it

Of course, transparency can only work, if you can be confident that your data matches the user experience. The MOS and other media and signaling KPIs provided by Qrystal pass this test with ease.

NFV / Virtualization

NFV / Virtualization

Network Function Virtualization (NFV) has a substantial impact on the design, deployment and management of communication networks. NFV architectures have the potential to reduce the costs of network operations while providing greater overall flexibility. Virtual SBCs, switches and other telecommunications functions are therefore becoming increasingly common.

The complexity of NFV environments with virtualized server and network infrastructures, newly distributed software functions and complex management systems are potential sources of issues requiring monitoring and troubleshooting. With all the benefits of NFV, your VoIP NFV system should not become a black box.

For many years Voipfuture customers deploy Qrystal in virtual environments. The Qrystal Manager and its different components can be easily deployed in an NFV environment. This is specifically done by tier-1 CSPs which require scalability and flexibility in deployment. Qrystal Probes can also be virtualized, depending on the monitoring scope and volume. Full line rate monitoring of Gigabit links requires dedicated probe appliances to analyze the many million RTP packets per second.
