5060/5061 I see the TLS package, it is not a sip message. so I thing the
problem is futher.and only 3CX phone can register with my server.
Instead of ngrep you should use tcpdump to capture the whole SIP traffic

TLS-decrypting feature of Wireshark to analyze the decrypted SIP signaling.

Note: make sure to disable all Diffie-Hellman ciphers
