Various collaborative communications platforms exist, such as unified telephony systems, that may allow users of the system to communicate with one another for various purposes. For example, such systems may support multi-party communications, such as conference calls, web-conferences, virtual meetings, and the like. As is sometimes the case, one or more parties on a call may do most of the talking, with other parties participating in a more passive or listening role. In some such circumstances, the speaking parties may not be aware of changes in circumstances of other participants on a call, which can lead to confusion, for example, if a response, or other input is solicited from generally passive or listening party on the call. For example, such a passive or listening party may have become distracted from participation in the call, but due to their passive role on the call, the other participants may not be aware of the change in circumstance.
