What is a PBX?
A PBX is a private telephone network used within an organization. It handles internal calls between extensions and connects to the public telephone network for external calls. Modern IP-PBX systems run on VoIP technology and offer features like voicemail, call transfer, conference calling, and IVR menus.

A call center platform is purpose-built software for managing high volumes of customer interactions. It includes everything a PBX does, plus campaign management, predictive dialing, real-time dashboards, agent performance tracking, and queue management.
