Vodafone New Zealand selected Nokia Networks and its Voice over LTE (VoLTE) solution to conduct the first VoLTE call on a cloud-based IMS network. With this, the operator showcased its readiness to offer high-definition (HD) voice calls for its customers.

As a next-generation technology, VoLTE has multiple benefits for operators and customers alike. These include HD voice quality, faster call set-up times with voice continuity, and optimized performance under load. The overall data consumption and signaling load is also lower compared to over-the-top voice applications.

  • Nokia Cloud Application Manager* was used to run VoLTE over the cloud

Tony Baird, Technology Director, Vodafone New Zealand, said: “As New Zealand’s 4G leader, we’re committed to investing in our 4G network for the benefit of customers – VoLTE is the next evolution.

Ray Owen, Head of Australia and New Zealand, Nokia Networks, said: “Nokia Networks is proud to partner with Vodafone New Zealand to bring the first VoLTE experience to consumers in New Zealand. This is an important milestone – not only in New Zealand – but across the Asia Pacific region. It enables Vodafone’s customers to be among the first subscribers in the world to experience VoLTE.”
