    Meaning of the parameters is as follows:
+     * address - The address in form of SIP URI where to send a duplicate
+       of traced message. This parameter trumps duplicate_uri and allows
+       tracing to more than one server.
+     * correlation_id - A string with a correlation ID to be added to the
+       HEP header when using HEPv3. It's possible to use PVs.
      * mode - SIP messages to be traced. One can trace the current message
        (function can be called on either a reply or a request), the
        current transaction(the route must belong to a request) or the
        current dialog(the message has to be an invite).
