UniMedia Telephone Middleware Our R&D team has deep expertise in switches from manufacturers including Alcatel, Lucent, Nortel, Excel, and Avaya. Based on domestic switch manufacturers (represented by Keygoe switches from Shenzhen Dongjin Company, with Langshen being Dongjin’s overseas middleware partner), we have developed a highly advanced and powerful UniMedia middleware product. This product adopts an integrated plus distributed architecture. Since its launch, it has been widely recognized by users for its robust functionality and stability. In particular, its integrated graphical scripting workflow customization and single-step workflow debugging and tracking features greatly facilitate partners’ rapid integration of telephone voice capabilities into their business systems. iSoftCall Telephone Middleware The iSoftCall telephone voice middleware and smart telephone terminal are based on the SIP softswitch model and utilize the unified interface of UniMedia. They offer powerful functionality, especially the smart telephone terminal, which integrates embedded PCs, telephone gateways, and softswitch middleware into a router-sized device while retaining the full functionality of traditional call center products, providing customers with cost-effective, comprehensive telephone product solutions. The iSoftCall smart telephone terminal supports the feature of “call handling locally, business processing in the cloud,” making it particularly suitable for integrating with SAAS-based business systems. Langshen’s product series has numerous successful cases across various industries, ranging from small board-card call centers and voice value-added platforms with several thousand lines, to SAAS cloud call centers and large-scale call center applications with nearly a thousand agents.
