Blacklist PRO examines the dialed number for outgoing calls and checks whether it is included in a configured blacklist. If yes - and if the calling user does not also have a whitelisting entry for the dialed number at the same time - the call is terminated. Optionally, an announcement can be played beforehand, which can be uploaded in the module configuration. Callers who are affected by a blacklist entry can optionally be put through by entering a password. The use of a white or black listing can also be restricted to members of a group to be specified. The module effectively prevents calls to possibly chargeable telephone numbers or unauthorized calls to the office. User-specific whitelistings and a password query allow you to control permissions very precisely. In order not to lose track of a large number of possible rules, a detailed description can be given for each rule. |
