Conference Call Telephone

Conference call is defined by Wikipedia as a telephone call which includes more than one called party as wishes by the caller. The calling party will need to decide whether the called party can make a conversation during the call or whether they can only listen to the call and won't be able to speak during the call. The calling party can also call other party during the call to join them in the call conference. From this definition, a conference call is simply a voice call to many parties.
