    are you on CUCM or CME. If on CME you just need to put the firmware in a directory that the phone can get to for option 150. If on CUCM just upload the firmware to the CUCM.

    A good place to start is understand the IP phone bootup process. Here's a good starter doc covering everything from VLAN tagging to bootup sequence. https://supportforums.cisco.com/t5/c...s/ta-p/3127965

    Once you give that a read, start with the phone registration process next, https://supportforums.cisco.com/t5/c...m/ta-p/3109183

    Finally, learn how to add a device to CUCM, https://www.cisco.com/c/en/us/td/doc.../b08uspha.html
