Yangfan softphone扬帆软电话
The Yangfan softphone gives teams a simple, consistent way to make and receive calls on TeleSilLink routes, on the devices they already use.扬帆软电话让团队在已有设备上，以简单一致的方式通过 TeleSilLink 线路拨打与接听。
Supply-demand matching供需对接
A matching workbench pairs route demand with available capacity, so capacity finds buyers and buyers find reliable routes without manual chasing.供需对接工作台将线路需求与可用容量匹配，让容量找到买家、买家找到可靠线路，无需人工反复协调。
Built on the Shanhai Platform 运行于山海平台之上
TeleSilLink services run on the Shanhai Platform, a unified communications control plane. It brings routing and billing, concurrency control, workflow automation and an AI workbench into one place, so operations teams manage every service from a single console. TeleSilLink 的服务运行于山海平台这一统一通信控制面之上。它把路由与计费、并发控制、工作流自动化与 AI 工作台汇聚一处，让运营团队在同一控制台管理全部服务。
- Route & line management — define and compare routes in billing-aware terms.线路与路由管理——以计费视角定义并比较线路。
- Concurrency control — enforce concurrency limits per trunk and route.并发控制——按中继与线路强制并发上限。
- Workflow automation — turn repetitive provisioning into repeatable workflows.工作流自动化——把重复的开通操作变成可复用工作流。
- AI workbench — assist operations with the platform's AI workbench and skills.AI 工作台——用平台 AI 工作台与技能辅助运营。
