NTTドコモビジネスX expanded NTT CPaaS Voice and began offering SIP Trunking, bringing together 3 connectivity technologies with WebSocket and WebRTC. This enables the use of Voice AI Connect to link telephony and generative AI in real time.
NTTドコモビジネスX announced that it had expanded NTT CPaaS Voice, its voice channel for NTT CPaaS, and would begin offering SIP Trunking on 14 October 2026. This brings together 3 connectivity technologies—SIP Trunking, WebSocket and WebRTC—to create an environment that connects telephony and AI agents in real time. Companies can select the connectivity method suited to each use case and accelerate proof-of-concept projects. The company also set out a BYO Agent policy, offering an option that does not depend on a specific generative AI vendor.
A seminar is also planned, with an event on the use of voice AI to be held in cooperation with イレブンラボ. The seminar will introduce the concept of Voice AI Connect and the NTT CPaaS Voice lineup, and attendance will be free.
In addition to the seminar, NTTドコモビジネスX plans to publish a dedicated webpage detailing the features, use cases and pricing structure of the connectivity technologies. イレブンラボ is expected to provide implementation examples and demonstrations of voice AI technology, with specific case studies illustrating the future of telephone customer service.
