    Ok, so you say that the phones are using SIP but you configured telephony-service (Not SIP) and the firmware version you are using is clearly Skinny: load 7912 CP7912080004SCCP080108A.sbin

    What are your phones saying? Registration rejected or something else?
    My advice to anyone looking to advance their career would be to learn DevOps tools and methodologies. Learn how to write code in languages like Python and JavaScript. Not to be a programmer, but a network automation specialist who can do the job of 10 engineers in 1/3 of the time. Create a GitHub account, download PyCharm, play with Ansible, Chef, or Puppet. Automation isn't the future, it's here today and the landscape is changing dramatically.

    Post a Dir flash: and add this to your config: tftp-server flash:/phone/7912/CP7912080004SCCP080108A.sbin alias CP7912080004SCCP080108A.sbin


    You may need to modify the path if it is different than the one above. I checked to CME 8.6 firmware version guide and it looks like you have the right firmware for a 7912.


    I'm assuming that MAC address in the ephone 1 statement is one of your 7912's correct?


    What is the current firmware version on the phones under Settings>Model Information> Load files


    Another thing you can do is debug tftp events, plug your 7912 in and post the output. This is fun, you are going to learn to troubleshoot today! :)

    Try a factory reset on the phone. (most phones are hold down the # key while the phone powers up, once the headset, mute, and speaker buttons start to flash in sequence, push 123456789*0#)
    There's no place like ^$
