Tuning Applications for IP
A move to IP delivers the most value when a majority of applications and facilities are migrated to the converged network. Encouragingly, a global survey of 395 senior executives conducted by the Economist Intelligence Unit for AT&T shows that about 72% of firms will have shifted voice and data applications over to IP by mid-2008. Most companies are standardizing this integration by adopting "Web services." Session Initiation Protocol (SIP), for example, promises to provide useful support in integrating everything from voice and videoconferencing to advanced collaborative applications.
