Source note · SIP trace capture and ladder analysis
Wireshark can decrypt TLS using a key log file (preference tls.keylog_file), and this method works even when a Diffie-Hellman key exchange is used.

A key log file is a universal mechanism that always enables decryption, even if a Diffie-Hellman (DH) key exchange is in use.
