The system allows managing traditional voice and IP channels. It provides a full control of the communication process between the contact centre and the client as well as allowing processing incoming and outgoing calls made by the same agents.
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.
