You may find the NEC series phone systems at college campuses, businesses and offices across the nation. The NEC series offers an easy-to-use interface with many features and functions you can use to make calls and keep track of communications. One of those functions is limited conference-calling capabilities, allowing you to converse with two additional people at the same time.
