Revolutionizing Business Communication with AliveLine+Plus

On December 1, 2025, AliveNet, based in Shibuya, Tokyo, officially launched its innovative SIP trunk service, AliveLine+Plus, that allows businesses to utilize area codes from all 47 prefectures across Japan. This service is a major step forward in facilitating cloud migrations for companies by supporting number portability and enabling the use of regional area codes.

A New Era of Cloud Communication

The launch coincides with the introduction of the Two-Way Number Portability System on January 14, 2025. This new regulation permits companies to acquire city area codes where their physical locations—such as headquarters and branches—are situated, making it possible to utilize these numbers in cloud PBX (Private Branch Exchange) and CTI (Computer Telephony Integration) solutions. Previously, regional area codes were only linked to on-premises telephone lines, creating challenges for companies trying to transition to a cloud-based communication environment. The new system effectively removes a major obstacle, enabling:

• - Use of local area codes in a cloud environment
• - Easier migration of primary numbers to cloud PBX
• - Simplified setup of decentralized contact centers

In response to this regulatory change, AliveNet has developed AliveLine+Plus to address the evolving needs of the market.
