Abstract
A application relates to call barring. Typically, PBX systems have the ability to bar calls originating from both an individual phone and group of phones. However, with nomadism/hot-desking in large organisations comprising typically many PBXs, often from different manufactures, a PBX base call barring solution is unworkable. Consequently, a computer telephony based solution has been chosen. The call barring is performed on the CTI server () which receives from the user via a computer terminal () a request to set up a call from a source telephone terminal () to a destination telephone terminal (). The CTI server allows or blocks the call set-up request according to the call barring settings and forwards allowed call set-up requests to the PBX (), whereby the CTI server overrides the PBX call barring settings.
