Firstly, let’s read the user’s question: “I might have missed something in the documentation but I spent a lot of time trying to upgrade my 3PCC phones to Enterprise.
This is why I wanted to share it with you in a simple task list:
- download from CCO a 8800 firmware. .zip format, not .cop.sgn.
- unzip the files and share it with a TFTP server. I used a third party TFTP server and the CUCM too, both works.
- connect to the phone using the following URL: https://<IP Phone IP Address>/admin/advanced
- click on Voice tab and Provisioning.
- in Upgrade Rule field, put tftp://<TFTP Server IP Address>/<path if not in the root>/<Firmware name>.loads (exemple: tftp://1.1.1.1/sip88xx.10-3-1-20.loads)
- for Enable Enterprise Image Upgrade, select Yes.
- check if the Firmware upgrade is at it's default value (Yes) and click on Submit All Changes.
MIND not to unplug power during upgrade!!! We have lost one phone because of a bad network connector...
It would be good if Cisco could confirm as we purchased these phones on a SIP solution until the customer could migrate to CUCM. A search yields the below "bug" with the conditions and workaround
…
Conditions:
Upgrading 7821 from 3PCC firmware to Cisco enterprise firmware
Workaround:
Cross-upgrades between 3PCC and Enterprise firmware are NOT allowed for any Cisco IP phones.
