RE: T20P firmware from
Hi Istvan,
Usually, we have two methods of firmware upgrade:
1. Upgrade via Web User Interface. (Manually, from the local system for a single phone)
2. Upgrade Firmware via Auto Provisioning. (Automatically, from the provisioning server for a mass of phones)
I suggest that you can upgrade via Web User Interface.

Please go to below URL to get more information:


Yealink IP phones support using FTP, TFTP, HTTP and HTTPS protocols to download configuration files. If the webserver support to these protocols, You can use one of these protocols for provisioning. You can refer to below Auto Provisioning guide for more information:


Hope this helps!
