United States law requires multi-line telephone systems (MLTS) systems to provide direct dial access to 911 to report emergencies. It prohibits having to dial a prefix to reach an outside line. In addition, when a 911 call is placed on an MLTS system, the system must be configured to notify a central location on-site or off-site where someone is likely to see or hear the notification.  Examples of notification can include on-screen messages using a soft client phone application, text messages for smartphones, and email for administrators.   

Ribbon’s Emergency Call Notification API provides a notification framework within the Ribbon SBC to recognize that an outbound 911 has been placed and to actuate an SMS notification sequence (send a text messages) to the configured directory numbers/recipients via a supported SMS Service Provider.  For Release 9.0, the only provider supported is Kandy.

For SBC Edge 9.0, Kandy is supported as the SMS Service Provider.
