SIP (Session Initiation Protocol) and VoIP (Voice over Internet Protocol) are both technologies that enable voice communication over the internet, but they serve different roles within that framework. VoIP is a broad term that encompasses any technology facilitating voice calls over an IP network. SIP, on the other hand, is a specific protocol used to initiate, manage, and terminate sessions in a VoIP network.
In simpler terms, think of VoIP as the general method of making voice calls over the internet, while SIP is a set of rules that govern how those calls should be made and managed. SIP solutions often offer additional functionalities like call routing, video conferencing, and integration with collaboration tools, providing a more versatile and feature-rich communication solution for businesses.
