The system which description and realization is presented in this article is intended to expand existing solutions to the emergency services for the distribution of voice messages with pre-recorded content in order to inform target participants about critical events in their surroundings using multimedia tools, based on Session Initiation Protocol. The transmission of information via voice channel has, over other forms of distributed notification, the advantage that the target user is forced to pick up the call and listen to the message - so the information cannot be ignored or overlooked. Another benefit is more accurate addressing of target groups, and ultimately it can ensure the re-delivery of messages to users who have not heard them. The authors present their own method of sending pre-recorded messages, which are then tested in terms of the definition of the performance capabilities of the distribution network. Practical implementation thereafter demonstrates the advantages and use of the proposed solutions in a simulated environment.
