An intercom is a stand-alone voice communication system used within a building, small collection of buildings, or portably within a small coverage area. It is used on a wide variety of properties, from houses that only require one connection between a resident and the propertys entrance to multi-unit apartments that require intercom hardware to be installed in every individual apartment. Some intercoms are equipped with video, and their wiring can be connected to the outside with a few pairs while controlling an electric strike. Traditional intercoms and public address systems are composed entirely of analog electronics components, but many new features and interfacing options can be accomplished with new intercom systems based on digital connections.

However, in recent years, Intercom has become synonymous with a customer service platform that allows businesses to communicate with their customers through conversational, messenger-based experiences across the customer journey. Intercom is a complete customer service solution that combines automation and human support to resolve issues faster and boost customer satisfaction while reducing team workload. It allows businesses to convert more website visitors to qualified leads and customers with ABM, chatbots, and automated meeting scheduling. Intercom is used by organizations who want one automated, human, AI-powered customer service solution to meet all of their needs.
