Freepbx do not add extensions

Hello, I have CentOS, asterisk and freepbx I added extensions via web interface. Then I reload core (core restart gracefully).
When I try to registrer new IP-Phone (lg-ericsson 8802) in asterisk’s logs added

Registration from ‘"Security"sip:[email protected]’ failed for ‘’ - No matching peer found

In asterisk CLI I promted (sip show peers) and saw no new extension.
What did I do wrong?
