Overview
Aastra Technologies Limited was a Canadian telecommunications equipment manufacturer whose products connected residential, business, and institutional users to communications networks, including the Internet. The company was based in Concord, Ontario, and developed from an engineering consultancy into a supplier of enterprise telephony, network-access equipment, and digital communications hardware. Aastra was founded in Toronto in 1983, when Francis Shen and Hugh Scholaert acquired an engineering consulting company. Its early work served the defense industry. During the 1990s, the company moved toward telecommunications and began concentrating on communications equipment and systems. It became a publicly traded Canadian company in 1996, providing a platform for expansion through acquisitions. The company grew substantially by purchasing assets and business divisions from larger technology and telecommunications companies. In 2000, it acquired assets of Nortel Networks’ Access Solutions Division, including rights connected with manufacturing telephones under the Nortel name. In 2001, it acquired Lucent Technologies’ Digital Video business and Ericsson’s cable-modem business. Further expansion followed in 2002 through the acquisition of Nortel’s CVX and CSG Division and in 2003 through the purchase of the ASCOM PBX System Division. These transactions broadened Aastra beyond conventional telephones into enterprise private branch exchanges, network access, digital video, and related communications infrastructure. Aastra also pursued a stronger European position. In 2005, it acquired the Germany-based EADS Enterprise Telephony Business and the DeTeWe Telecommunication Systems business. Europe subsequently accounted for the large majority of the company’s sales, while the United States represented a smaller share and Canada a relatively limited portion. In 2008, Aastra acquired Ericsson’s enterprise PBX division, associated with the MD110 and MX-ONE telephony-switch platforms. This strengthened its presence in large-scale enterprise voice systems and made the company an important consolidator in the business-telephony sector. Its product portfolio included residential and business telephone terminals, screen telephones, enterprise PBX systems, network access terminals, cable-modem-related equipment, and digital video encoders, decoders, and gateways. Some residential telephone equipment was sold in the United States as Bell equipment through the Sonecor brand, which represented Southern New England Telecommunications. The company therefore operated across both end-user communications hardware and the infrastructure supporting enterprise and network services. Mitel Networks announced on November 11, 2013, that it would acquire Aastra in a transaction combining cash and Mitel shares. The announced transaction was valued at approximately 400 million Canadian dollars according to the cited reference material. Mitel completed the acquisition in January 2014. Aastra ceased to operate as an independent company, and its products, technologies, and operations were integrated into Mitel’s portfolio. Mitel subsequently provided information about the treatment of former Aastra products, while the Aastra corporate identity progressively disappeared from the market.
History
Aastra began in Toronto in 1983 when Francis Shen and Hugh Scholaert acquired an engineering consulting company. The business initially provided services to the defense industry. During the 1990s, it redirected its activities toward telecommunications and developed into a manufacturer and supplier of communications equipment. Aastra became publicly traded in Canada in 1996. The company’s subsequent growth relied heavily on acquisitions. In 2000, Aastra purchased assets from Nortel Networks’ Access Solutions Division, including rights associated with manufacturing telephones under the Nortel name. In 2001, it acquired Lucent Technologies’ Digital Video business and Ericsson’s cable-modem business. It expanded again in 2002 through the acquisition of Nortel’s CVX and CSG Division, followed in 2003 by the purchase of ASCOM’s PBX System Division. Aastra’s international enterprise-telephony presence increased significantly in 2005, when it acquired the Germany-based EADS Enterprise Telephony Business and DeTeWe Telecommunication Systems. The company’s sales were strongly concentrated in Europe at that time: Europe accounted for approximately three quarters of sales, while the United States and Canada represented much smaller proportions. In 2008, Aastra acquired Ericsson’s enterprise PBX division, whose products included the MD110 and MX-ONE telephony-switch platforms. Aastra’s product scope covered residential and business telephone terminals, screen telephones, enterprise PBX systems, network-access terminals, cable-modem-related equipment, and digital video encoders, decoders, and gateways. Its residential telephone products were also sold in the United States as Bell equipment through the Sonecor brand, representing Southern New England Telecommunications. On November 11, 2013, Mitel Networks announced an agreement to acquire Aastra in a transaction involving cash and Mitel shares. The transaction was described as having an approximate value of 400 million Canadian dollars. Mitel completed the acquisition in January 2014. After completion, Aastra no longer operated as an independent company. Its technology, products, and operations were incorporated into Mitel, and the Aastra brand subsequently ceased to have an independent market presence.
