+ * This enum defines the information message severity.
+ *
+ * The ZRTP implementation issues information messages to inform the user
+ * about ongoing processing, unusual behavior, or alerts in case of severe
+ * problems. Each main severity code a number of sub-codes exist that
+ * specify the exact nature of the problem.
+ *
+ * An application gets message severity codes and the associated sub-codes
+ * via the ZrtpUserCallback#showMessage method.
+ *
+ * The severity levels and their meaning are:
+ *
+ * <dl>
+ * <dt>Info</dt> <dd>keeps the user informed about ongoing processing and
+ * security setup. The enumeration InfoCodes defines the subcodes.
+ * </dd>
+ * <dt>Warning</dt> <dd>is an information about some security issues, e.g. if
+ * an AES 256 encryption is request but only DH 3072 as public key scheme
+ * is supported. ZRTP will establish a secure session (SRTP). The
+ * enumeration WarningCodes defines the sub-codes.
+ * </dd>
+ * <dt>Severe</dt> <dd>is used if an error occured during ZRTP protocol usage.
+ * In case of <em>Severe</em> ZRTP will <b>not</b> establish a secure session.
+ * The enumeration SevereCodes defines the sub-codes.
+ * </dd>
+ * <dt>Zrtp</dt> <dd>shows a ZRTP security problem. Refer to the enumeration
+ * ZrtpErrorCodes for sub-codes. GNU ZRTP of course will <b>not</b>
+ * establish a secure session.
