Functions of UCaaS.

    Enterprise Telephony

    Enterprise Telephony services are enterprise-grade versions of residential VoIP and business VoIP solutions that provide large organizations with advanced features and functionality such as private branch exchange (PBX) capabilities, conference calling, desk-to-desk calling, music on hold, and automation attendants.

    Unified Messaging

    Unified Messaging is the integration of different forms of communication media that are all stored in one system, implemented into a single interface. In most traditional systems, messaging systems relied on their own systems, servers, or standalone devices.

    Communications-enabled business processes

    CsEBP is the integration of communications capabilities into software-enabled business procedures, applications, and technologies. CEBP enables communication between applications as well as between applications and humans to automate many components of business processes. The purpose is to optimize those processes and to ensure continuous, low-latency, real-time communications among the customer, suppliers, and employees of an enterprise.

    Meetings (audio/ video/ web conferencing)

    The term “web conferencing” encompasses collaboration technologies that enable users to place calls via an application over the internet, through software downloaded locally to a computer or device, or in an on-premises environment.

    Instant messaging and presence
