Whenever you choose to connect to an existing VPN network or choose the option to Add a New VPN Connection, a dialog displays to warn about the potential disruption of emergency response numbers. You can proceed to the VPN connection step by pressing OK. You can dismiss the dialog and cancel the connection by pressing the Back button on your device.
The text of the Emergency Response Notification dialog for VPN networks follows here:
CAUTION - Emergency response numbers (for example, 911 or 112) may not work on software telephony clients. Your exact location and the appropriate emergency response agency may not be easily identified. Some countries restrict use of VoIP software via VPN over the Internet, including: UAE, Saudi Arabia, Pakistan, Lebanon, Jordan, Egypt, Oman, Qatar, Yemen, Algeria, and Kuwait.
