Cloud-native VoLTE: an enabler for flexible network evolution

Voice over LTE (VoLTE) has emerged as an efficient and effective way of delivering voice on next generation networks while improving quality for end users.

While voice services do not necessarily drive customer acquisition or increase monthly average revenue per user, they remain an essential network service for CSPs: there is a real risk that subpar services could drive customers away. There are, therefore, valuable efficiency and quality benefits from investing in VoLTE infrastructure. Not least, compared with legacy technologies, VoLTE uses finite radio resources and energy much more efficiently, improving network economics.

This whitepaper uncovers how cloud-native IMS and VoLTE network functions provide a cost-effective and practical first step in a transition to a more agile cloud-based business while ensuring continued foundational voice and messaging telecommunications services.
