Protection of real-time data such as voice data exchanged as packets between a mobile electronic device and a VPN gateway during a media session over a communications link that includes a wireless network. A first VPN connection is established between the mobile electronic device and the VPN gateway through the communications link, the first VPN connection using key-based encryption to protect data exchanged therethrough. While the first VPN connection is established, a second VPN connection is established between the mobile electronic device and the VPN gateway through the communications link, the second VPN connection using key-based encryption to protect data exchanged therethrough.
