Have you ever thought about that or not, but conference calls really unites the world – as they let us connect people from any country in a virtual phone space reality letting conduct conversations for any period of time. It means that many people can hear each other simultaneously.
Conference calls are very convenient for business purposes, and mostly used in business, although they let connect people on the party line – where one can meet new people.
Conference calls services allow providers create “configurations” so that people can listen and speak during a call, and can be limited to listen-only access.
As a rule, to get connected to the conference call service – i.e. to make a conference call, one must dial a 800-number and follow the instructions. Usually a caller has to enter an extension and provide the password to get connected.
The other way to use conference calls is to connect people which have the same interests from different parts of the world and you. Probably, there you can meet new people, but anyway conference call less often used for this purposes.
