 5 Return Codes
 **************
 
 Each line of the SSIP output starts with a three-digit numeric code of
 the form NXX where N determines the result group and XX denotes the
 finer classification of the result.
 
    SSIP defines the following result groups:
 
 1XX
      Informative response -- general information about the protocol,
      help messages.
 
 2XX
      Operation was completely successful.
 
 3XX
      Server error, problem on the server side.
 
 4XX
      Client error, invalid arguments or parameters received.
 
 5XX
      Client error, invalid command syntax, unparseable input.
 
 7XX
      Event notifications.  See ⇒Events Notifications in SSIP.
 
    Result groups 1XX and 2XX correspond to successful actions, other
 groups to unsuccessful actions.  Only the groups defined here may be
 returned in an SSIP connection.
 
    Currently, for return codes in the range '100'-'599', only the
 meaning of the first digit of the result code is defined.  The last two
 digits are insignificant and can be of any value.  Clients shouldn't
 rely on the unspecified digits in any way.
 
    However, the return codes in the range '700'-'800', reserved for
 events notification, are well defined in the appropriate section of SSIP
 documentation and client applications can rely on them.
 
    In the future, these return codes should be fixed so that clients can
 rely on them.
