Increasingly popular in the corporate environment, UM is the integration of different electronic messaging and communications media (email, texts, fax, voicemail, video messaging) technologies into a single interface, accessible from a variety of different devices. While traditional communications systems deliver messages into several different places all of which have to be independently checked – voice mail on the answering machine, e-mail on the laptop and faxes on a machine in the corner for instance, with Unified Messaging all types of messages are stored in one system which can be accessed from a computer or smart phone.
