Emergency Response Notification
The text of the Emergency Response Notification displays the
first time that you open the Call application and also when you
select an existing VPN network or add a new VPN network.
Emergency Response Notification for Call Application
When you open the Call application for the first time, the Emergency Response Notification dialog box alerts you that your ability to dial emergency numbers may be hindered because you are using a VoIP network.
This dialog requires that you check the "I acknowledge this information" check box and tap OK in order to dismiss the dialog. After the initial acceptance, the dialog reappears only if you perform a factory reset of your device or the system administrator performs a remote wipe of your device.
The text of the Emergency Response Notification dialog for the Call application follows here:
Dialing emergency numbers (for example, 911 or 112) may not work on an enterprise-class IP telephony network like that used for Cisco DX650. Correct location information may not be passed on to emergency responders. Your network administrator can advise you about the capabilities of your network, including the dialing sequence that you will need to use when on or off the enterprise premises.
