VoIP

Voice over Internet Protocol (VoIP) is a technology that enables voice communication and multimedia sessions over the internet instead of traditional telephone networks. By converting voice signals into digital data packets, VoIP allows calls to be transmitted over IP networks, such as the internet or private intranets.
VoIP reduces costs compared to traditional phone systems, offers flexibility for remote and mobile users, and provides advanced features like video calls, voicemail-to-email, and call forwarding. Popular VoIP applications include Skype, Zoom, Microsoft Teams, and enterprise telephony systems.
Advanced
VoIP works by digitizing analog voice signals, compressing them, and transmitting them as data packets using protocols such as SIP (Session Initiation Protocol) or RTP (Real-Time Transport Protocol). These packets are then reassembled into audio at the destination.
Advanced VoIP systems integrate with unified communications platforms, enabling voice, video, messaging, and collaboration tools on a single interface. They often leverage cloud hosting for scalability and redundancy. Quality of Service (QoS), jitter buffering, and echo cancellation are critical to ensuring clear and reliable communication. VoIP can also support encryption for secure calls, making it suitable for businesses handling sensitive communications.
