6. Virtualization Initiatives Add To The Open Hardware Options For Customers To Consider When Deploying Next-Gen Voice And UC Solutions And Help Better Support Both Enterprise Data Centers And Mid-Market All-In-One Packaging Proprietary Appliance Virtualization Enabling Voice/UC Co-residency  Traditional voice system packaging on separate, proprietary boxes produced by the manufacturer  Limited synergies with the rest of the customer’s IT environment Appliance w/Open Components Virtualization Enabling Data Center Consolidation Software-Only on 3 rd Party Server DescriptionExamples  Legacy TDM Systems  Call control and other communication applications run on open operating systems like Linux  Manufacturer utilizes open processor components to reduce costs but produces turnkey appliances for the customer to ensure availability  Voice system vendor produces only the software-based elements of the voice and UC applications  Customers and/or systems integrators chose third-party servers and devices based on guidelines and/or certifications  The provider utilizes virtualization technology to place multiple voice and UC applications onto a single server produced by them  This may save space and reduce power consumption while allowing the provider to position their full software suite at once  Voice and UC applications are delivered as software-only solutions that run on an open virtualization platform  This allows these applications to be deployed on common hardware with business applications deployed in the data center  Most mainstream IP-PBXs  Microsoft OCS/Lync 2010  Siemens OpenScape UC  Interactive Intelligence  Avaya Aura System Platform  Lotus Foundations (ShoreTel, NEC)  Mitel vMCD  Siemens OpenScape UC  Cisco UCS 6 Desktop Virtualization  Thin-client desktop devices running all user communication and productivity applications displace the current PC model  All major user applications are shifted to centralized data centers broadly supporting the organization  Mitel/Sun Ray  Mitel/VMware View  Cisco VXI

7.  What are the compelling reasons a customer should implement a next-generation voice platform, UC, and/or Collaboration solution today given the lingering economic uncertainty?  What types of changes are providers seeing in the content and process through which customers define the requirements of RFPs they submit for new voice and UC solutions, and what further changes are anticipated over the next few years?  How are vendors and their channel partners changing their sales approaches to more broadly engage LOB, functional departments, and user communities without alienating traditional voice and IT stakeholders?  Is the current RFP process effective in defining the needs of this broader audience and demonstrating value to these evolving stakeholders in the vendor responses?  Are the most compelling business cases for deploying next-generation solutions currently based more on traditional IT cost considerations or on the productivity and business process enhancements enabled by their flexibility and interoperability? How will this change over time?  Are UC and Collaboration solutions best delivered through a multi-vendor approach built around interoperability or through a single provider delivering a tightly-integrated, end-to-end architecture?  How large a role will solutions blending premise- and cloud-based capabilities play in delivering targeted UC and Collaboration functionality to specific business segments and users compared to current premise-only offerings?  What are the potential advantages and disadvantages of implementing cloud-based and blended solutions today, and how is that likely to evolve over time?  Virtualization has emerged as a key area of development and emphasis among enterprise voice providers over the past 12 months, but does it have customer appeal and value beyond large-enterprise data centers?  How are the business process benefits of targeted UC, Collaboration, and CEBP capabilities enabled through next-generation architectures quantified, and what changes does this require in the sales process beyond addressing the technical considerations of implementing new delivery approaches? This Panel Will Address A Range Of Questions On How Providers Are Using These Evolving Architectural Alternatives To Better Respond To Both Current And Future Enterprise Requirements
