Extension-based Recording Solutions

Here a tap is placed on each extension that should be recorded. So it is possible to selectively tap only some phones in an organization. However, phones and phone links are often vendor specific and the technical standards for these are not published or only available to partners of the phone system vendor. So compatibility to system phones can not be achieved in all cases. The last option in this case is to tap the receiver/handset/headset cable, which does only carry the audio signal without any additional signalling information.
