In September 2007 Inter-Tel and Mitel concluded the final details of their merger. The merger combines Inter-Tel's strength in the US and UK, its enterprise muscle and its call centre clout with Mitel's global reach and brand leverage.

• The merged company will be the top North American SMB networking player (1), second in the Western Europe IP PBX market (2), and the overall leader in the UK communications market (3).
• Combined revenue in excess of $800 million USD
• Combined market coverage in excess of 90 countries
• Increased R&D activity benefiting both brands
• A shared commitment to open standards
• Greater product choice from two trusted brands
• A commitment to existing product lines and customers
• A commitment to 'open' industry standards, such as SIP, XML and CSTA
• Extensive portfolios, covering unified communications, networking, management and networked applications
• A broad choice of solutions from the very small to the very large, from IP-enabled to pure IP unified communications, from standard solutions to tailored, from single site to multi-site

Mitel will maintain Inter-Tel's Arizona headquarters, which will become the centre of operations for the combined US business and serve as an important centre of R&D excellence.

"Inter-Tel's people, products, managed services and partnerships complement those at Mitel. The merger will enable us to accelerate our growth by extending our small-to-medium business (SMB) leadership position"
Don Smith CEO of Mitel
