I´m configuring the new VPN Phone feature with a CCM 188.8.131.5200-8, IP Phone 7942 (Firmware: SCCP42.9-0-3S) and a ISR 2811 12.4(24)T3 Advance IP Services as SSL VPN Server.
When the IP Phone tries to connect from internet, the phone prompts the username and password, and after few seconds the phone displays VPN Authentication Failed (Status Messages: All Concentrators Failed).
In fact I can connect to the SSL VPN from a PC but not from the IP Phone. I attach some files with information about the configurantion.
Any idea for this problem? I hope you can help me.
Thanks in advanced.
