Conference Phones
Conference phones are meant for holding conferences between three and a bigger amount of participants. This allows all participants listening and speaking simultaneously. Usually the conference is begun by the participant having “Conference Phone”. Other participants call to a special number for a conference which connects them with “Conference Bridge” that joins all lines together.
The system of Classes of Service (COS) helps defining rights for one or another extension in the PBX or Centrex systems. For example, few groups require more space for storing voice messages, while other need the redirection of calls to cell phones, the third does not have to make calls outside of the office network. With the help of this system one can change and configure settings.
