Summary:A method and an apparatus are disclosed that manage the held calls for an off-premises terminal at the system that extends calls to the terminal, such as a private branch exchange or other type of data-processing system, instead of at the system that is receiving the extended calls, such as a mobile switching center at which a cell phone is registered. The disclosed technique is based on the observation that the extending system knows of an incoming call to an off-premises terminal before the receiving system. As a result, the extending system can advantageously select the calls that it holds versus the calls that it sends to the receiving system. The extending system can control the routing costs and provide a consistent look-and-feel of call control to the off-premises terminal user.
