VoIP, or Voice over Internet Protocol, allows users to make phone calls using an internet connection rather than a traditional phone line. It has various professional and personal uses. Professionally, it enables conference calls between offices without needing to be in the same building. Personally, it can be used for voice chat on video game consoles, connecting gamers around the world. VoIP works by converting voice into digital signals sent over the internet, then converting them back at the receiving end. A major advantage is a standard monthly fee rather than per-call charges, though calls to regular phones may have additional costs. It has increased online gaming connectivity and console accessory sales.
