It appears that coverage appearance buttons aren't alerting the user's Communicator desktop app, only the deskphone back in their office. I can't find any documentation that says this won't work but I am assuming it is by design. They have Power User and Softphone licenses and are release 10.1. I'm not too familiar with what softphones still work with this release and thought it was only Communicator and am curious if there is another solution that will work so she can be alerted of calls to 3 other people.
