If they are not even looking for TFTP, then from the phone, hit

I understand that I
must pay for a support license to download Cisco firmware, so I’m not
trying to pirate it. I simply want to know what I need to buy in order to get
firmware files for my phones. Does anyone have any helpful links they can give?
What does this license cost?
