Call voice over IP (VoIP) refers to the transmission of voice calls over the internet rather than traditional phone lines. VoIP converts analog voice signals into digital data packets, which are then transmitted over the internet. This technology has gained popularity due to its cost-effectiveness, flexibility, and advanced features compared to traditional phone systems.
VoIP offers numerous benefits, including cost savings on long-distance and international calls, increased flexibility with features like call forwarding and voicemail, and integration with other communication channels such as instant messaging and video conferencing. Additionally, VoIP has played a significant role in expanding communication access to remote and underserved areas.
