and when caller call callee, i use ngrep to catch package through port 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 to a file. Later open the pcap file in Wireshark and use the TLS-decrypting feature of Wireshark to analyze the decrypted SIP signaling.
Note: make sure to disable all Diffie-Hellman ciphers
