ABSTRACT:
Methods, and communications devices employing such methods, of controlling communications with at least two calling party devices by a user of a called party device. A first call link is established between a called party device and a first calling party device. The called party device then receives a call request from a second calling party device; e.g., a call-waiting indication. A user of the called party device places the first call link on hold, and accepts the call request from the second calling party device to establish a second call link between the called party device and the second calling party device. While the user of the called party device is in communication with the user of the second calling party device, the user can cause a message to be transmitted to the first calling party device, whereby the user of the called party device can communicate information to a user of the first calling party device without interrupting communications with a user of the second calling party device. A message to the first calling party device can, for example, instruct the user to hang up, continue to hold, or leave a message for the user of the called party device.
