Unified Communications (UC) integrates many communications such as phone, chat, and video conferencing. It enhances productivity and provides ways to interact across different communication channels. Unified Communications as a Service streamlines communication solutions across the enterprise. It provides real-time video conferencing, chats, SMS, and even contact center capabilities. Since UCaaS works over the internet, you don’t need any extra VoIP hardware to serve customers. UCaaS providers are responsible for security, backend configuration, and telephony functions.
