We have a few dozen 7900 and 8800 phones connected to 11.5 CM using ASA AnyConnect. All these phones were initially setup at the corporate office where they got their VPN profile and latest firmware load. Now that they are out in the field how do we upgrade their firmware? I suspect I have to expose my TFTP server to the Internet and have users enter the public IP in the alt TFTP field? Is there a more secure and easier way?
Thanks,
Diego
