Call Filtering (Blacklist / Whitelist)
Defne’s Call Filtering (Blacklist/Whitelist) application provides the control mechanism for incoming/outgoing calls and SMS messages for subscribers. It enables subscribers to bar or allow voice calls and/or SMSs from members specified in the subscriber's barring (black) or allow (white) lists.
Subscriber may select either blacklist or whitelist mode for activation. If blacklist mode is activated, all call and message traffic originated from subscribers in the blacklist are blocked. Moreover, all call and message traffic terminated to subscribers in the blacklist may be blocked, if required.
On the other hand, if whitelist mode is activated, only call and message traffic originated from subscribers in the whitelist will be allowed, all other traffic will be blocked. Similarly, only call and message traffic terminated to subscribers in the whitelist may be allowed, all other traffic would be blocked, if required.
