We have a customer that ask us the following feature: For each extension we want an enabler (a badge or a numeric password digitized with the telephone keys). The enabler must identify the user (So Jim have a badge or a code, Tom another one and so on). Before each call our users must use the badge or hit the key on the phone, identifying themselves on the system. This feature first of all trap unauthorized calls from telephons placed in places where all people could use it. Second one if the data was stored in the system we can stats who has called who, following the identifier as main key and associating with it the destination number Now, do you have some ideas how we can implement this feature with 3CX? Please note, the customer can change the phones with that suggested by you and with badge (if needed). But the problem's focus is the possibility to enable or not a call depending by the security key and the possibility to trace the identifier/call couple. Could you give me an help about this?
