Unify is a company with significant influence in the field of communications. Unify, formerly known as Siemens Enterprise Communications, inherited Siemens' traditional advantages in engineering technology. In 2013, Siemens Enterprise Communications was renamed Unify, becoming an independent communication software and service company. In 2023, Unify was acquired by Ottawa-based communications company Mitel to strengthen its unified communications and collaboration product lineup.

Unify focuses on providing unified communication software and services, and is committed to integrating various networks, devices and applications into an easy-to-use platform. Its product line includes communication system equipment such as group telephones, among which the OpenScape Business series is one of its main products.

In addition to hardware equipment, Unify also provides solutions such as system integration, debugging, installation, maintenance, and technical consultation and technical services related to equipment application.

Through acquisitions and expansion, Unify has a collective customer base of over 75 million users in more than 100 countries and has built a network of more than 5,500 dealers, service providers, technology and strategic alliance partners.
