LINE WORKS Corporation has collaborated with Santsu Telecom Service Co., Ltd. To provide a flat-rate telephone answering service to call centers and retail stores. This service adds on Santsu Telecom Service’s Clacall SIPTrunk telephone line connection service on top of the LINE WORKS AiCall telephone answering service utilizing the AI telephone answering system.
This enables companies to introduce AI to manage incoming calls through their current 0120-toll free number on their existing number. Clacall SIPTrunk can be used together with existing PBX and CTI systems, so that companies can upgrade their voice system to provide AI-based telephone support without replacing the existing system. Santsu Telecom Service will supply the service.

The service has three key benefits for companies First, the costs of the telephony and AI are set and firm, so companies are not hit with extra charges when the volume of calls increases, saving on telephone support costs.
