How can I configure the SIP phone to receive settings automatically?

Question

Asterisk

Good afternoon, colleagues.
We have a small handful of office phones, mainly this: Yealink SIP-T20P.
I would like to set up automatic receipt of the settings of these phones by MAC.
As I understand it, you need to dig towards DHCP, but how to configure the server?
In general, if anyone has come across this, clarify, poke your nose. Links to manuals are welcome.

Start with this document .
In general - DHCP server points to FTP/TFPT/HTTP/HTTPS server with configs (option 66 and/or 128). First, the config associated with the model is loaded, then by the MAC address of the device.
