Deploying IP telephony enables a globally distributed enterprise to communicate and to operate as one integrated entity. This allows new business models to emerge that increase productivity and speed business change, all on a single network. The question for any business is how best to implement this critical technology. Decisions are driven by how network telephony applications and capabilities match business needs while meeting IT requirements for reliability, security, interoperability, and manageability. The telephony market has coalesced around a common IP telephony architecture consisting of open servers, highly distributed gateways that connect IP and traditional TDM elements, and a broad range of new access devices, including IP phones, wireless phones, softphones, PDAs, and more. Avaya business communications applications are based on open standards and can be tailored to match specific customer needs and company sizes. Avaya has the right IP telephony solution for any business. Our flagship software, Avaya Communication Manager, can be delivered over several telephony server and gateway options for mid- to large-size enterprises. Avaya Distributed Office serves enterprises with hundreds or thousands of branch offices. Avaya IP Office is designed specifically for small to midsize operations, and Avaya Quick Edition is perfect for very small businesses. Any evaluation of an IP telephony solution should include a thorough TCO (Total Cost of Ownership) analysis, which compares the characteristics, costs, and ROI (Return on Investment) of different vendors’ solutions. According to a 2007 Nemertes Research study, which interviewed 125+ enterprises that have implemented IP telephony, Avaya has the lowest TCO of all major vendors for deployments of 1000+ endpoints. The study named Avaya as having the lowest capital and operational start-up costs, the result of our investment protection philosophy with flexible implementation timelines, coupled with extensive management tools and comprehensive support. |
