You can purchase the MCC 3100 for Windows Mobile with or without an
integrated Virtual Private Network (VPN) client. The VPN client enables
secure calling from within the Enterprise wireless network or from internet
hotspots. After connecting through the VPN, all other applications on the
device use the VPN tunnel.
Nortel does not support third-party VPN clients with the MCC 3100 for Windows
Mobile. You can use only the MCC 3100 for Windows Mobile with VPN for VPN
connectivity.
