Unified Communications (UC) integrates multiple communication tools—such as voice, video, messaging, and content sharing—into a single, cohesive platform, typically delivered via the cloud (UCaaS) to enhance productivity and collaboration. By breaking down communication silos, UC enables seamless interaction for hybrid and remote teams, reducing costs and improving responsiveness. 

SIP trunking is a modern communication method that uses the internet (VoIP) to replace traditional phone lines, letting businesses make and receive calls and multimedia (voice, video, text) over a single data connection. It connects a business's Private Branch Exchange (PBX) system to the Public Switched Telephone Network (PSTN) virtually, offering cost savings, scalability, and unified communications by consolidating services onto one IP network.
