Enable TCP in Asterisk 16.5.1

hello I have mounted an asterisk system in my home and I can not get me to take the tcp, just udp.

As much as I put in sip.conf these lines, as I see in all the manuals on the Internet, I can not make it work:

tcpenable=yes
tcpbindaddr=0.0.0.0
transport=udp,tcp

He’s just listening for you.

You know what I’m missing?
Thank you
