Nokia Networks announced successful Voice over LTE (VoLTE) call using Zain’s commercial LTE network in Kuwait. For the live HD (high-definition) voice call and video capability, Nokia Networks used its VoLTE solution, and services expertise to successfully conduct the project which involved making and receiving HD voice calls while simultaneously accessing data services over the LTE network.

Nokia Networks’ VoLTE solution consisted of its IMS (IP Multimedia Subsystem), Subscriber Data Management, and Open TAS (Telecommunications Application Server). Open TAS provides supplementary services that are applicable for voice, messaging, and video sessions for subscribers in LTE and other broadband networks.

In addition, the company’s Professional Services for VoLTE helped the operator ready the network all the way from architecture and design to end-to-end multi-vendor integration.
