Abstract
A specific code indicative of a specific request is used to provide a communication device with an ability to send specific calls, such as emergency calls and silent calls, and the ability to distinguish the specific calls from the received calls. A method of sending a call includes generating a specific code indicative of a specific request, adding the specific code to a call, and then sending the call to a receiver for notifying the receiver of the specific request. A method of receiving a call includes determining whether a received call comprises a specific code indicative of a specific request, and generating an indication in response to the specific request when the received call is determined to comprise the specific code.
