====== Martec System Interface ===== The Martec System Interface (MSI) is an add-on feature that can receive serial communications from a safety management system, telling the 7.00 to call specified extensions and play an emergency alert message. This feature does not come standard on the 7.00, but can be purchased separately. //By default, the base software is installed on the system, but must be licensed before it can be configured or used.// **Currently, the MSI only communicates with a safety management system (SMS) provided by Martec.** If you are interested in learning more about the MSI feature and whether it can be configured to serve your particular application, please contact DuVoice Sales for more information.
