What capability do most modern CAD systems include that allows linked users to communicate via messages?

Most modern Computer-Aided Dispatch (CAD) systems have integrated instant messaging capabilities, which facilitate real-time communication among linked users. This feature is essential for effective coordination during incidents, as it allows dispatchers and field personnel to share critical information quickly and efficiently. Instant messaging supports immediate response and collaboration, ensuring that everyone involved in a situation is informed and can act accordingly.

While voicemail, video conferencing, and email notifications are useful communication tools, they do not provide the same level of immediacy and interactive engagement as instant messaging does. Voicemail does not allow for real-time conversation, video conferencing requires more resources and setup time, and email notifications can often result in delays in communication. This makes instant messaging the most suitable option for the rapid exchange of information in a fast-paced dispatch environment.
