A more limited set of features can be deployed to users that gives Click-to-Call functionality. This enables the end users to click a user within their Lync contact list and have it dial the user’s number from their legacy PBX phone. Additionally, presence messages are integrated so that when a user places a call from the legacy phone, his or her presence in Lync automatically updates to In a Call. This is the scenario Remote Call Control provides to end-users.
This is one of the most basic integration options and does not provide a significant amount of flexibility or features to the end user. In this state, call-forwarding settings, delegation of calls, and advanced call control features are not available. The Click-to-Call features also do not work well for remote users because even if they initiate a call, it places the call from a desk phone inside the office, attached to the local PBX.
