Agents are human or virtual, and they appear in one list distinguished by a
badge — because a caller dialling an extension cannot tell which answered, and
mostly should not need to.
A budget. A team can be cut off while the organisation still has credit.
Part of what a login can see. A supervisor’s scope is their teams.
Moving an agent between teams therefore moves their call costs and their
colleagues’ visibility, not only their campaign work. It is the right
behaviour of the model, and it is not what somebody staffing a campaign
expects — so the roster dialog says so.
A virtual agent has a profile rather than a handset — see
virtual agents. It can hold an extension, so a
caller reaches it by dialling; it can also have none at all, which is the shape
a campaign-only agent takes.Nothing downstream — queues, campaigns, routing, billing, call records — assumes
an agent is a SIP extension.
