Abstract
A telephone care system enables personnel monitoring an emergency response center to be reminded that help is still needed at a given location. The system includes a provision for sending a plurality of alarm messages, wherein one criterion for selection of the message being sent is whether a message was previously sent without the alarm state thereafter having been terminated. In a preferred embodiment, a communication system in accordance with the invention includes a provision for sending repetitively, after an initial alarm message, a message to the effect that "help is still needed" until the alarm state has been terminated.
