Rejected Call

Call rejection can apply both to incoming and outgoing calls. However, since most call centers forbid dropping the caller (without explaining why the call cannot be answered), for the inbound version of this, rejection is primarily for re-routing calls on a network level.

Generally, the rejected call scenario works either with RouteTypeDefault and an empty destination to reject the route request (using the default route destination as configured on the switch), or RouteTypeCallDisconnect to reject the call. (RouteTypeReject has been deprecated since it is switch-specific.) Two scenarios are applicable here. Rejected Call (Route Point) shows this with a route point involved, and Rejected Call (Route Queue) shows it with a route queue.

The following graphic and table describe a rejected call (route point).
