Abstract
In one embodiment, the operating logic of a first communication interface device, a callee, is enhanced to include logic for transferring a direct inward dial data call it received from a second communication interface device, the caller, to a third communication interface device, the transferee, where the first communication interface device and the third communication interface device are coupled to the same PBX. The operating logic of the second and the third communication interface devices, the original caller and the transferee, are also enhanced to include logic for cooperating with the first communication interface device to effectuate the transfer. In one embodiment, the operating logic of the first, second, and third communication interface devices are further enhanced with the enhancements provided to the second and third, first and third, and first and second communication interface devices respectively, to allow each of the three communication interface devices to be the caller having its call transferred, the transferor callee, as well as the transferee callee, at different points in time.
