We have Poly Edge E450 IP Phone.  I know we can set up the intercom to another user but I need to know how to set up intercom to a group or multiple users?  I know the phones have a paging system, but we need to be able to have an individual pick up the phone anywhere in the building.  We don’t have employees that stay in one place all day.  We need to be able to say “Jane?” and have that user pick up an extension closest to them and be able to talk back to the user initiating the intercom call.  Literally right now what we’re doing is “Jane, call John back at his extension.”
