Organization Concepts for Unified Communications

Application and Services layer, including the application software and other information and software services provided to the support the user interfaces and business processes. This includes all server-based applications and the supporting hardware both in-house and hosted (Software as a Service). In Unified Communications, this layer includes the server or services-layer software that provides the functions of PBXJIP-PBX, voice mail/unified messaging, e-mail, I M, presence, audio/video/web conferencing, directories, mobility services, user portals, etc. In some situations, it may be appropriate to have distinct teams for sets of these applications (e.g. often there is an e-mail/unified messaging team or an IP PBX/Conferencing team).
