now i have cisco DX-80 and i want to register it and configure using option 66 in DHCP server but it seems that it can't reach the server to provision itself and when i try to find what happened using wireshark, i see that it is trying to establish session on destination port 80 but it can't how this can be possible. As i know that option 66 for tftp server ip address.

Option 150 (TFTP) for Cisco phones and devices. This is a known fact, probably since the first Cisco CUCM came out 20 years ago.

Yes, what @b.winter said! I can't remember if the first version of CUCM I installed was 3.1 or 3.2 (when it still ran on Windows 2000 Server), but it was no later than 3.2. DHCP option 150 has ALWAYS been the first choice. I believe there may be some fallback to option 66, but 150 is the preferred (and best IMHO) way.
