Deep Contextual Bilingualism

We go beyond simple translation. Our team conveys technical nuances and business intent accurately, ensuring seamless communication between global clients and China's major telecom operators.

Proven Implementation Experience

With nearly 20 years of deep immersion in the local China VOIP industry and engagement with hundreds of multinational clients, we possess unmatched operational knowledge to avoid deployment pitfalls.

Global Models, Local Execution

We deeply understand Western VOIP business models and technical architectures. Crucially, we bridge this with China's unique regulatory and operational environment, delivering compliant, proven solutions.

Decades of Operator Relations

Through 20 years of partnership with China's top three carriers, we have built deep trust and operational pipelines. This enables us to handle complex or specialized requests that standard processes cannot accommodate.

CTS acts as your dedicated technical implementation partner in China. We are not an operator. Instead, we are the bridge that helps global enterprises deploy and manage SIP Trunk and Microsoft Teams Direct Routing within China's unique telecom ecosystem.

Since 2007, we have provided in-depth consulting, technical troubleshooting, and full operational support, ensuring our international clients navigate China's VOIP landscape smoothly and in full compliance.
