Unify is a telecommunications company focused on enterpriseunified communications. It is headquartered inMunich, Germany, and is subsidiary ofMitel since 2023.[1] It was known asSiemens Enterprise Communications (SEN) until January 21, 2016, it was a joint venture betweenThe Gores Group andSiemens.[2] Originally announced July 29, 2008, SEN started operating in 2013, with Gores having a 51% stake, while Siemens had 49%. In October 2023, Mitel completed the purchase of the company.[3]
Siemens Communications traces its origins toSiemens & Halske(German legal name:Telegraphen-Bauanstalt von Siemens & Halske) founded byWerner von Siemens on 12 October 1847. Siemens' first invention was the pointer telegraph.[4] In the latter half of the 19th century, the company built long-distance telegraph lines, encompassing major projects inGermany andRussia, and the monumentalIndo-European telegraph line stretching over 11,000 km fromLondon toCalcutta.[5] In 1897, Siemens & Halske went public.
During the first half of the 20th century, the company undertook a series of mergers and spin-offs, leading to the formation of three separate companies. The original company, Siemens & Halske, focused on communications engineering.Siemens-Schuckertwerke was founded in 1903 to develop electric power engineering. Finally, in 1932,Siemens-Reiniger-Werke was founded to specialize in electro-medical equipment.[6] In 1966, through a major restructuring process, these main companies merged to formSiemens.[7]
In the late 1970s, Siemens focused oninformation and communications technology (ICT). In 1978, it established Siemens Communication Systems, which, in 1985, was reorganized into two divisions: Siemens Communication Systems for public network products, and Siemens Information Systems for PBX and computer-related products.[8][9] Entering theglobalization era of the 1990s, these two divisions made acquisitions. In 1989, the PBX division initiated a structured purchase ofROLM fromIBM, renaming it ROLM Systems, and completed the purchase in 1992 as Siemens-ROLM Communications.[10] The same year, the company acquired a 40% stake inGEC Plessey Telecommunications (GPT) which evolved into the UK operations of the current company. In 1991, the carrier networks division acquired Stromberg-Carlson from The Plessey Company plc.[8] In 1996, thePBX businesses ofMercury Communications, a subsidiary of UK-basedCable & Wireless were also acquired.
In late 1998, Siemens undertook a major restructuring into four main divisions: power generation, industry, rail systems, and information and communications (ICN).[11] As part of the ICN Division, Siemens Information & Communication Networks (SICN) — later to be commonly known asSiemens Communications (Siemens COM) — became Siemens's biggest business unit.[12] Its focus was toInternet-based network technologies, as it was predicted that global data traffic volume would surpass voice telephony traffic in the early part of the 21st century. In addition, Siemens COM placed greater emphasis on the US market, dominated at the time byNortel,Lucent, and the emergingCisco; to that end, the company made two American acquisitions, Castle Networks and Argon Networks in 1999.
In March, 2002, Siemens Communications was divided into two major business units - one for public mobile networks and fixed networks; and the other for enterprise networks.
The evolution of Siemens Enterprise Communications began in June, 2006, when Siemens divided Siemens COM into two pieces.On June 19, 2006, the carrier networks business was merged withNokia's Network Business Group to form a new joint venture,Nokia Siemens Networks. On October 1, 2006,Siemens Enterprise Communications was created as a wholly owned subsidiary of Siemens. Since then, the business focused on unified communications.
In late July 2008, Siemens announced a joint venture with American private equity company The Gores Group (headed byAlec Gores), integrating two Gores Group businesses,Enterasys Networks and SER Solutions.[13]
Enterasys operated as a subsidiary of Siemens Enterprise Communications until 12 September 2013, whenExtreme Networks, announced that an agreement to purchase Enterasys in an all-cash transaction valued at US$180 million.[14]
In October 2013, Siemens Enterprise Communications was rebranded to Unify.[15]
In November 2015 it was announced that IT services companyAtos would purchase Unify fromThe Gores Group/Siemens for 340 million euro.[16] The acquisition was completed in January 2016.[17]
In January 2023, Atos announced it entered into exclusive negotiations withMitel for the sale of its Unified Communications & Collaboration business (Unify).[18]

Its primary product brands are OpenScape (unified communications applications), HiPath (converged enterprise communications) and Circuit (SaaS Team Communication). The company announced OpenScape withMicrosoft in 2003.[20][21] Unify demonstratedSIP andservice-oriented architecture with OpenScape. The company's services covermanaged services,professional services, and maintenance and support services.
On 28 October 2014 Unify launched aSaaS Team Communication product calledCircuit which was previously codenamed Project Ansible.[22][23] Due to agreement between the new owner Atos and former owner, from 2016 Circuit was further developed on-the-go and in 2017 launched as a unified communication and collaboration platform for the whole Siemens.[24]
