Result
The phone disconnects the VXC VPN tunnel and
leaves the phone VPN tunnel intact.
Cisco VXC traffic receives permission to go over the
phone VPN tunnel.
The phone attempts to reuse the phone VPN
credentials for the Cisco VXC VPN tunnel silently
without considering the VXC Challenge field.
If the VPN concentrator is configured for one-time
password, the attempt fails and the phone displays
the VXC VPN Sign In window, which prompts the
user to enter a different password.
