Abstract
Many multinationals have now embarked on network convergence and the
implementation of IP telephony. IP convergence is increasingly being driven by
the need for improved mobility as well as an expectation of cost savings.
Unified communications (US) applications are on the agenda for the majority of
the companies we talked to. These companies are not looking for a single
supplier for UC, but expect the IP telephony and software collaboration
vendors to have a strategy of interoperability.
