What is Enterprise VoIP?
Enterprise VoIP (Voice over Internet Protocol) is a cloud-based phone system built for large, distributed organizations. It replaces traditional phone systems and on-premises private branch exchange hardware by transmitting voice over the internet, delivering HD call quality, lower costs, and the infrastructure to support thousands of simultaneous users across every location.
An enterprise VoIP phone system is built for scale, supporting multi-site and global teams with seamless CRM and helpdesk integrations. It unifies voice, messaging, and SMS on one platform while providing real-time caller context. With AI-powered transcription, smart call routing, AI voice agents, and analytics, it improves workflows and boosts team productivity.
