On January 15, 2026, the CTTL Terminal Labs (hereinafter referred to as "CTTL-T") of the China Academy of Information and Communications Technology (CAICT) successfully passed the certification re-review of the French telecom operator Orange with its profound technical accumulation and excellent comprehensive strength, and was authorized by the new 5G voice test program. This milestone achievement fully reflects the firm confidence of both parties in win-win cooperation, and is also a high recognition of the laboratory's technical capabilities, and also highlights the hard-core influence and leading position of CTTL-T in the field of international communication testing and certification.

The continuation of this authorization is of great significance, and the iterative upgrade of the certification system has become the core highlight. The upgraded Orange HD Voice certification system adds a forward-looking 5G voice test plan, forming a complete system covering three test plans: HD Voice VoIMS, HD Voice EVS VoIMS and HD Voice EVS Vo5G. This update not only accurately anchors the development trend of 5G technology, but also further improves the voice quality evaluation system for VoNR scenarios, setting a new benchmark for the high-quality development of the communications industry.

The upgrade of the certification system will eventually benefit end users. Terminal devices that pass this certification can realize cross-network ultra-high-definition voice calls (HD Voice+), covering various scenarios such as VoLTE, VoWiFi, and VoNR. Whether using VoLTE calls on 4G networks, VoWiFi calls based on Wi-Fi, or VoNR in 5G environments, users can experience clearer and more stable voice quality. Especially under the 5G network, call quality is significantly improved, the voice is pure and realistic, and the communication experience is smoother.

The continuation of the Orange certification authorization is a strong demonstration of the comprehensive strength of Taylor's terminal laboratory, and it is also a confirmation of its leading position in the international certification system. It fully demonstrates the laboratory's profound technical accumulation and professional service capabilities in the field of 5G voice testing and evaluation. In the future, CTTL-T will continue to deepen communication technology innovation, and contribute more to the development of the global communication industry with professional technology and rigorous attitude.

Laboratory testing service scope:

CTTL-T supports 2G/3G, 4G VoLTE, 5G VoNR, VoWIFI (supports WIFI6e), VOIP multiple network access, and the service product types cover mobile phones, tablets, VoIP phones, vehicle terminals, real-time interaction/conference equipment, smart glasses, smart watches and other information and communication products.
