Total Payback Period is Less Than Eight Months

OTTAWA, 2012-01-19 14:00 CET (GLOBE NEWSWIRE) --
Mitel® (Nasdaq:MITL), a leading provider of Unified Communications and
Collaboration (UCC) software solutions, today announced the results of a
commissioned study conducted by Forrester Consulting, a leading independent
research firm, that focused on the financial impact of deploying Mitel's
virtualized UCC solutions. The study titled "The Total Economic Impact of Mitel
Virtual Solutions" provides a framework for businesses to evaluate the costs
and benefits of deploying Mitel Virtual Solutions within their organizations. 

As part of the study, Forrester interviewed an enterprise with 600 employees
across multiple sites about its experience implementing Mitel's virtualized UCC
solution. Forrester found a three-year, risk-adjusted Return-On-Investment
(ROI) of 84 percent, and a total payback period of 7.8 months. 

According to the report, the organization also realized the following benefits
after deploying the solution: 

  -- Productivity savings with Unified Communications (UC) and better user
     experience
  -- Cost avoidance of an alternative, non-virtualized, voice solution and
     corresponding annual support
  -- Cost savings from utilizing SIP trunking
  -- Failover savings from using software-based technology
  -- Hardware and disaster recovery savings from virtualization infrastructure
  -- IT administrative savings through faster recovery
  -- Training and cost avoidance
  -- Cost savings from better scalability
  -- Lower risk from downtime
  -- Increased flexibility for future growth and new capabilities
