本帖最后由 fayawang 于 2020-3-30 12:48 编辑 我找到的一个关于upgrade的介绍是英文版的希望对你有帮助。但我没有实际测试过。
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:
1. download from CCO a 8800 firmware. .zip format, not .cop.sgn.
2. unzip the files and share it with a TFTP server. I used a third party TFTP server and the CUCM too, both works.
3. connect to the phone using the following URL: http://
/admin/advanced
4. click on Voice tab and Provisioning.
5. in Upgrade Rule field, put tftp:////.loads (exemple: tftp://1.1.1.1/sip88xx.10-3-1-20.loads)
6. for Enable Enterprise Image Upgrade, select Yes.
7. check if the Firmware upgrade is at it's default value (Yes) and click on Submit All Changes.
