The document provides an overview of VoIP (Voice over IP) technology, including what it is, some key concepts to understand, benefits and drawbacks. Specifically: - VoIP allows voice calls over IP networks using protocols like SIP and codecs to compress audio into digital packets, replacing traditional phone systems. - Benefits include lower call costs, flexible configurations for remote work and additional features. However, VoIP relies on network quality and has potential for jitter or voice quality issues. - Implementing VoIP can significantly reduce phone expenses, especially on international calls. It also enables remote work and adds scalability compared to traditional phone systems.
