IMS Fixed

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.
