Abstract: A communication system is described. The communication system includes a communications device that is arranged to conduct communications via a communications network to a first communications address, and a security component arranged to receive input security keys. The communications device is arranged to initiate a communications event to a first communications address in response to the security component determining that an input security key matches any one of a plurality of security keys available to the security component. By initiating the communications event in response to determining that the input security key matches any one of a plurality of security keys available to the security component, the communication system provides a secure method of initiating the communications event.
