Our Recent Project for One of the Customers

In our latest engagement with a Network Node vendor, we successfully completed one of the contracted projects, referred to as Service Control and Voice, for its client an operator in the UK. It was a transformation project wherein the operator replaced their 4G core from Huawei to Nokia. Celcom resources were part of this journey from deploying a new Mobile core for Voice (cloud-based VoLTE/VoWiFi solution) across four data centres on the Telco Cloud, integrating with the operator OSS/BSS and other downstream systems, training, and handover to Operations. Celcom has provided E2E Project Management, Integration Leads, SMEs, and Automation Expert support to the project. The contribution provided by Celcom resources was well acknowledged and appreciated by both Vendor and Operator Management.
