In R75.40VS and above, these predefined SIP services are available:

  • TCP:sip_tls_authentication - Used for unencrypted SIP over TLS (that is, authenticated only). NAT is not supported for connections of this type.
  • TCP:sip_tls_not_inspected - Insecure way of allowing SIP over TLS to pass without inspection.
