News Facts:

• [ Mitel® ] (NASDAQ:MITL), a trusted provider of [ unified communications ] software solutions, today announced that Summit Automotive has standardized its voice architecture with [ Mitel ] in order to meet the speed, deployment, and scale needs of its rapidly expanding family of automotive dealerships.
• Summit Automotive Partners, a member of the Booth Creek Management, LLC portfolio, selected [ Mitel ] as its communications provider. This decision is based on Mitel's robust and flexible architecture and seamless integration of voice and data in a virtualized environment.
• Summit has already begun deployment of the Mitel Communications Director (MCD), [ Mitel Unified IP Client for Sun Ray™ ], and Mitel Applications Suite (MAS), in concert, across its entire existing dealership group.
• Mitel's ease of deployment and flexibility is consistent with Summit's growth strategy. That strategy necessitates Summit to meet standard vehicle manufacturer requirements on retooling within a 72-hour window when there is an ownership change.
• The flexible deployment architecture of MCD allows Summit to loosely couple locations into a highly adaptable and resilient network, and decouple if they choose to divest a location.
• The nature of Summit's distributed dealership network and decoupling requirements drove a company-wide thin client strategy. [ Mitel Unified IP Client for Sun Ray ] provides simplified and secure authentication for both voice and data, allowing unified hotdesking for enhanced workforce flexibility. It also enables Summit to drop thin clients into place and configure credential information in the back office which simplifies desktop management while reducing costs.
• Enhancing Summit's thin client strategy is Mitel's pedigree in virtualized voice. In the future, it will allow Summit to seamlessly leverage existing VMware® investments with both the Mitel voice and Sun Ray environments. These environments will be virtualized to complement Summit's IT efforts on best practices.
• The enterprise grade, flexible and high performance Mitel technology is matched by its Mitel TotalSolutions Program (TSP), which helps Summit effectively plan for expenditures on an operating expense basis. This enables Summit to streamline investments and increase project cost accuracy to a low single digit percentage point. This is essential in the strategy through which Summit grows its business.
