Call blocking is available on Lync 2010 and 2013 and Skype for Business 2015 and 2019 platforms. When the recording system is experiencing technical difficulties and is unable to record conversations, it can block all new calls and disconnect ongoing calls if possible for configured recorded users. This feature allows mitigating the risk associated with not recording a certain conversation.
- Voice, video, screen and application share calls, instant messages, and P2P file transfers can be blocked.
- The system blocks all calls for the configured recorded users, so it is most suitable for always-on recording scenarios.
- The components participating in call blocking (SfB/Lync Call and IM Filter Service, Proxy Service) are logging details of each call that has been blocked into an audit log file (lync_im_filter_auditlog.csv, lync_call_filter_auditlog.csv).
- Ongoing calls can only be blocked when proxy based recording is used, otherwise, only new calls can be blocked.

A basic call blocking feature is available with the 1Global (formerly Truphone) integration. If there are no recorders at the time of call establishment, the call can be blocked. |
