[Asterisk-Users] Cisco 7960 SIP Craziness...

[Dan]

Hi,

Take care which version of the firmware you try to upload.
The new version (5.x) is digitally signed and you will not be able to do any
downgrade in the future.
You will not be able forever to upload any firmware which is not digitally
signed by Cisco.

BR,
Dan
