I saw a previous post about this problem but no one seems to have a real solution for it... I have a few Cisco IP Phones 7960 that I want to install at remote locations. I can easily setup my router to forward the ports of Asterisk BUT I don't want to open my TFTP server over the Internet as all the SIP configs are in clear text... I was first of all considering making VPN connection between my main office and the remote locations but that's fine if I have VPN routers on both side. But if someone use a phone at home and they have no router or cheap ones I'm stuck... I won't ask everyone to purchase a VPN Router just to have the phone working. I know I could open a second TFTP server just for the few phones that are not on my network and leave the Name, Authentification Name and password empty in the SIP config file and add it manually on each phones but I would still need to provide the SIP firmware and all the other files open on the internet... In the Cisco phone I don't even see a way to change the default TFTP port but even that solution doesn't seem good enough... Anyone having a working setup? Thanks Martin

[Asterisk-Users] Cisco phones config over internet
Martin, In the 7960s (my firmware is P0S3-07-3-00), you can press "settings" and then #9 to unlock the phone. From the settings menu, #3 will take you into Network Configuration. Near the bottom (#25), you must disable DHCP and Save. Then, from within the Network Configuration menu, you can manually enter the TFTP server (#7). BTW, what are the potential difficulties with someone seeing the config files?
