A notification method for providing camp-on capability includes utilizing device-to-device signal exchanges via a data network. As a result, the camp-on capability may be enabled at a called communication device by means of a signal sent from a calling communication device. In the preferred embodiment, the data network is the global communications network referred to as the Internet, but this is not critical. As a response to the determination that the called communication device, such as the telephone, is in an unavailable condition, a first notification signal is transmitted from a calling communication device to the unavailable called device. The first notification signal may be an application program that is automatically executed at the called device. Alternatively, the first notification signal may be a special protocol element that triggers execution of a camp-on program stored at the called device. The first notification signal includes the network address of the calling device. When the executed program determines that the called communication device is available to receive an incoming call, a second notification signal is transmitted to the original calling device. In response, the original calling device reinitiates the process of establishing connectivity with the called device.
