NEC ASPIRE MULTI BUTTON TELEPHONE. If you and your co-workers handle each other's calls, you might want to be in a Department Callinggroup (page 37). Someone calling your group's number goes through to any- one who's available. You can even have Department Step Calling (page 39) send your personal calls to your group when you're not avail- able. To answer a call already ring- ing a co-worker's phone, use Group Call Pickup (page 54). When you're on a call and you want the others in your area to listen in on the conversation, activate Group Listen (page 55). Your co-work- ers hear the call through your telephone's speaker. If you frequently call the same co-worker, you can have Ringdown (page 105) automatically call them for you.
