This report was written to help organizations decide which Unified Communications solutions to implement while in the planning phase. The market of Unified Communications is split up in equipment, services and integration. While Microsoft and Cisco dominate in the equipment and services markets, both Hewlett-Packard and IBM dominate the integration markets. Their services include assessment, strategy and architecture services. As such, they are the two only companies capable of helping users to plan their Unified Communications transformation. Of these two, only Hewlett-Packard delivers full integration services and additional equipment such as smartphones and notebook computers on the Microsoft / Cisco platform.
