What is intercom for?
First of all, intercom is used for holding meetings in a format when there are several users with two-way communication, who can not only listen, but also speak, and there are users only with the ability to listen to speakers. Participation from several users and up to hundreds of participants is assumed. The intercom format has appeared for holding meetings at enterprises or government agencies, when the participants are at a distance from each other. The discussion is held between several speakers while the rest are just listening.
During intercom at an enterprise or in a government institution, it is understood that only speakers and senior managers communicate, and the listeners are the heads of departments or teams to receive instructions.
To implement communication, telephone lines and special selector devices are used, which make it possible for branched communication and settings, with the help of which the roles of participants as a speaker or listener are rigidly defined.
The use of intercom is convenient and affordable. This saves time for interlocutors and money for travel for the sake of a meeting It is enough to agree in advance on the date and time of the conference and invite (notify) all the prospective participants in the conference call.
Intercom use cases
With the advent of modern communications, mobile networks and the Internet, conference calls have become widespread not only in enterprises, but also in social communication. Such a service is in demand when it is not possible for several people to meet at the same time to discuss specific issues or for joint communication. In its modern form, selector communication can be carried out not only on the basis of a telephone line, but also through a computer network with program control.
There is a role-playing conference call that is carried out for social communication in a multi-presenter, two-way, multi-listener format. Special software is used for this.
The format of audio or video conference has become very popular, in which, by default, all participants have two-way communication and can both speak and listen. Communication programs such as Skype or TeamSpeak and RaidCall, common among users of online games, are designed for this format. To implement exactly the intercom, the division of roles among the participants is carried out programmatically or by simple agreement. So, in the last two programs, the creator of the channel, that is, the communication session, can, as administrator, allow some participants to speak, and leave the rest only the opportunity to listen.
