Metaswitch is the first company to deliver a complete VoLTE solution built using cloud native software methodologies. Mobile network operators can deploy our VoLTE solution in public, private or hybrid cloud environments using lightweight Containers.

By virtualizing our components at the OS level instead of at the hardware level (as with the VM / hypervisor approach), we have dramatically reduced overheads, which enables orchestration systems to instantiate our virtualized network functions (VNFs) instantly to provide capacity on-demand and resilience when required.

  • Cloud native VNFs
  • Designed for deployment in public, private or hybrid clouds
  • Runs in Containers and compatible with MANO systems
  • IR.92 and IR.94 VoLTE
  • IR.95 VoLTE peering and roaming
  • IR.51 VoWiFi
  • Includes diagnostics and analytics tools
  • Supports any VNF manager
  • Supports MANO layers

Why use Metaswitch’s VoLTE and VoWiFi solution?

With the spectral efficiencies of VoLTE and the coverage possibilities of VoWiFi, the momentum is increasing towards end-to-end packet-voice, using both licensed and unlicensed spectrum. Although VoLTE demands a complete overhaul of service infrastructures, it is a fundamental requirement for mobile network operators.

Our cloud native virtualized network functions running within highly orchestrated container clusters can deliver infrastructures and applications that are cost-effective, agile, elastic and resilient.

  • Quickly enable VoLTE coverage and services
  • Offload coverage and traffic to unlicensed spectrum with VoWiFi
  • High quality voice and a foundation for next-generation services
  • Our cloud native software is robust, scalable and flexible
  • Avoids the high overheads and costly redundancy of virtual machines running in a hypervisor environment
  • Automated instantiation and lifecycle management can save time and resources
  • Supports 5G network slicing for highly efficient QoS and QoE metrics for specific applications
