Communication service providers (CSPs) face big challenges when putting their NGN, LTE or IMS networks into service. Still, the vision of using one all-IP communication infrastructure to provide various services promises increased revenue and higher customer loyalty trough triple play and other service bundling. Customers appreciate value-added services, yet their baseline expectation regarding VoIP is predetermined by the quality known from the traditional PSTN. In other words, CSPs can only gain a competitive edge, if they maintain excellent voice quality. This is easier said than done, since there are many potential reasons for VoIP voice quality impairments. Furthermore, impairments can originate in a CSP’s own network as well as in the networks of customers and interconnection partners.

The Solution

VOIPFUTURE’s passive RTP Monitoring solution is essential to CSPs for keeping their voice service under control. VOIPFUTURE enables CSPs to

  • assess and document the speech quality of all actual VoIP calls,
  • offer service level agreements (SLA) for voice quality,
  • optimize their network,
  • quickly identify the root causes of problems and to
  • pinpoint responsibilities in shared infrastructure and interconnection scenarios

This information is critical to guarantee a premium voice service whilst ensuring an efficient use of resources. It enables CSPs to optimize their IP networks for the sensitive voice service. Furthermore, the unique VOIPFUTURE KPIs allow CSPs to offer voice quality SLAs, which takes Customer Experience Management to a new level.

Carrier-Grade RTP Monitoring

The VOIPFUTURE solution is perfectly suited for large carrier environments. The RTP Monitoring Probes are capable of analyzing 1 GbE links at full line rate and also support monitoring of 10 GbE links. The probes generate a detailed metric for every 5s segment of each stream. This metric is called the quality data record (QDR). The collected data is transferred to the Application Manager for post-processing, correlation and to calculate KPIs. The Application Manager features a high-performance database cluster that is designed to handle and store data relating to billions of call minutes and thus caters even for the largest carrier networks. All in-call information, including the detailed QDRs, is available for weeks and can be accessed by other OSS and BSS systems.
The VOIPFUTURE solution is essential for CSPs who want to set standards in voice quality.
