Customer Pain Points

Aging Equipment and
Declining Stability

Existing digital trunk gateways and SBC devices in current networks have generally been in operation for more than 6-10 years. Hardware aging has led to increasing failure rates and declining system stability, seriously threatening service continuity.
Non-Compliance with Localization and
Autonomous Control Requirements

Existing network equipment lacks autonomous and controllable capabilities and cannot meet the financial industry's Xinchuang Localization replacement strategy, nor comply with security protection requirements for critical information infrastructure.
Ensuring Secure Access for
Carrier SIP Trunks

SIP Trunks transmit services over IP networks, introducing security risks such as cyberattacks, toll fraud, and information leakage. Professional SBC deployment is therefore essential to ensure secure SIP Trunk access.
Security Assurance for
WebRTC Agents

With the comprehensive upgrade of omnichannel services in financial contact centers, internet-based services such as WebRTC web calling, video customer service, and remote video signing are experiencing explosive growth. How to achieve secure, compliant, and controllable WebRTC agent access to enterprise core platforms over the public internet has become a key challenge and critical pain point in the digital transformation of financial institutions.
