Emergency calls:
When a user dials an emergency number from the REDCOM Secure Client application on a device with telephony support, the application is designed to transmit the dialed digits to the native cell dialer of the mobile device, where the user can then attempt to end the emergency call via his voice network of the mobile operator. After passing the dialed digits to the native dialer, the application is no longer involved in the call attempt. The emergency call, once made, and all associated location services are the responsibility of the mobile operator. By default, the app treats “911” as an emergency number and forwards 911 calls to the native dialer.
The user can reconfigure the list of known emergency numbers in the application, which allows him to control which numbers dialed, if any, are transmitted to the native dialer. Dialing emergency numbers from the app on a device without telephony support or reconfiguring the app to prevent emergency numbers from being forwarded to the native dialer will cause the app to process any emergency call such as a VoIP call on the data network. Such calls may fail due to any interruption in the application’s ability to communicate with its VoIP network service, such as power outages, lack of data network connectivity, etc. Making a call through the VoIP network to report an emergency can also result in the inability to direct the call to the appropriate emergency response center or the inability to determine the correct location for the user. For these reasons, REDCOM recommends that emergency calls be made over the cellular operator’s network using the device’s native dialer, if available. For devices without telephony support, REDCOM recommends that users always have another means of accessing emergency operator services in the event of a VoIP service disruption. REDCOM will not be responsible for any errors, delays, costs, damages, injuries or deaths resulting directly or indirectly from the use of the Secure Client application for emergency calls.
