Voice service quality is vital to ensure an excellent customer experience. Nokia can offer a complete high-quality Voice service on all technology generations from 2G to 5G and a seamless evolution between the generations.

What is Circuit Switched Core?

The Circuit Switched Core (CSC) is used in certain legacy systems and specialized applications to deliver voice services in 2G and 3G systems. Nokia's CS Voice solution supports Cloud deployments and ensures seamless interworking with 4G Voice. It benefits from the inter-application synergy in Cloud and the efficiency and innovation of data centers. Nokia Open MSS and Open Multimedia Gateway products constitute the world’s most proven Mobile Softswitch. It has an extensive worldwide installed base and excellent performance record. It ensures a superb customer experience by resilient High Definition Voice.

Customer Experience Through Voice Services

Improving the customer experience is a fundamental way to differentiate from your competitors and the evolution of voice services plays a key role in that effort. Even though VoLTE is just around the corner, yet still need to support 2G and 3G voice subscribers efficiently, while guaranteeing a seamless evolution to VoLTE, with no disruptions to your customers, while also cutting costs.

It’s vital to take a strategic view with any Rel-4 solution installed providing a clear evolutionary path to VoLTE and the Telco Cloud. Innovation is the leading motivating factor in Telco Cloud deployment.
