A company with many branch offices will inevitably face the difficulties in communication. Pinnacle Technology (ACLAS brand), a high-tech enterprise, headquarters in Taipei and sets two factories in Xiamen. As the company scales up in size, the communication and cooperation between headquarter and branch offices become increasingly costly and inconvenient with the traditional telephony system. By installing the Yeastar S100 IP PBX and S300 IP PBX respectively in the Taiwan headquarter and Xiamen branch offices with peer to peer networking, all ACLAS employees from different sites can be synchronized with efficient communication and the company also benefits from high productivity.


Pinnacle Technology Corporation is a Taiwanese manufacturer established back in 1982, with headquarter in Taipei and two factories including R&D center (about 110 engineers) located in mainland China. Pinnacle develops, manufactures, and sells innovative commercial devices under ACLAS brand, which have been registered in 50 and 32 countries respectively.


As a high-tech enterprise, Pinnacle keeps enlarging its scale with increasing number of employees to meet its needs in developing, manufacturing and selling. It inevitably brings some difficulties to the enterprise management, especially in the communication and cooperation.

  3. Every plant has its independent loud speaker. However, it is not feasible to broadcast unitedly to the entire factory.
  4. Two traditional PBXs were installed because of the expansion of the department. But the department extensions connected to different PBXs cannot dial each other directly.
  5. The existing automated attendant setting is outdated with few lines, which largely affects the customer call completing rate.
  6. Three sets of telephony system cannot be managed in a unified way, which is likely to lead to the disorder of the lines, extensions and the inbound and outbound rules.


Yeastar put forwards an IP PBX solution for ACLAS after fully understanding its needs and situation.

  1. Install the S100 IP PBX and S300 IP PBX respectively in the Taiwan headquarter and Xiamen branch offices and connect the two IP PBXs with peer to peer networking through the Internet.
  2. Replace traditional phones with the IP Phones and register them to the respective Yeastar IP PBX through the local area network.
  3. Install the IP Call Box in the plants that have loud speakers by registering the IP Call Box as one of the Yeastar IP PBX extension and connect it to the Power Amplifier.
