How to power sip t-22p via PoE?

Question

Telephony

Actually, I have been using it for more than a year, but the other day I just visited a third-party site, it was said that it is possible to power the device via PoE, that is, the power should be transmitted through a twisted pair cable. yealink is behind nat, connected to a ZyXEL Giga II router, I would like to free the socket and get power over a twisted pair cable (in my case, a patch cord), I tried to hook another patch cord into the connector, but the miracle did not happen (((in the web muzzle yealink' but I didn’t find anything like that, it’s a shame to call the help desk with such a question))) tell me how to give power to the patch cord?

Answer 1

You need something like this adapter http://www.dlink.ru/ru/products/1366/.
The adapter includes a power supply.
Plug the patch cord from the ZyXEL Giga II into the DATA IN port.
From DATA OUT to yealink.
