It is possible to interact with Finesse without logging in?  From what I’ve gathered, it seems like you can in a limited way with Poster, i.e. changing Agent states.  However my team was wondering if a program like Poster (perhaps written) can send a request to an Agent to take a call? If the Agent is on a call, then we can have an interaction perhaps a Screenpop for the Agent to hold and accept or reject the call. Is this a possibility? Or can this be done only in Finesse, login in as a Supervisor?
