Course overview
Voice remains a core service with strict quality expectations. This program covers IMS in depth and the end-to-end behaviour of VoLTE and VoNR including RAN dependencies, so engineers can design, integrate and troubleshoot voice services.
Who should attend
- Core and IMS engineers
- Voice quality and optimisation engineers
- Integration and test teams
Prerequisites

Frequently asked questions
Live online programs are delivered in real time by an instructor over video with shared labs and interactive Q&A. Classroom programs are delivered face to face in Dubai or other GCC locations, with the instructor and lab environment in the room. Both use the same curricula and instructors.
Programs are built on 3GPP, O-RAN and industry standards and are vendor-agnostic by default. Corporate deliveries can include vendor-specific parameter mapping and scenarios where required.
Participants who complete a program receive a Teleriu certificate of completion. Teleriu programs are professional technical training and are not affiliated with any certification body unless explicitly stated.
