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.
The group (ANWAR NAJD) was established in 1978 as a supplier and installer of power transmission line. In 1987 we have entered the IT market as a system builder and a retailer under the name BITCOM.
