I'm setting up a SIP trunk with TLS encryption and need to know which TLS protocols and cipher suites are supported by the 3CX Phone System for this purpose.

Specifically, could you please provide a list of:

  • Supported TLS protocols (e.g., TLSv1.2, TLSv1.3, etc.)
  • Supported cipher suites
This information will help me configure our SIP trunk securely and ensure compatibility.
