unified messaging

Synonymous with integrated messaging and multimedia messaging.The integration

of voice, audio, text, facsimile, image, and video messaging, ideally on a single messaging platform or on a suite of platforms interrelated in such a way as to be transparent to the end user. Unified messaging is intended to provide an end user with a single interface to a messaging system or suite of messaging systems that support all types of messages in all formats, and that can adapt the message format to match the limitations of the terminal device and network that the end user employs to access the messaging system.

For example, a unified messaging system could convert a fax message into a voice message if the user calls from a conventional telephone over a landline, or into a text message if the user has access to a cellular telephone. Ideally, unified messaging works in both directions, enabling the recipient of the message to respond in an inverse manner. If, for example, a unified messaging system converted a fax message into a text message for a user who has access to a cellular telephone, unified communications allows the user to
