Within the floating part, floating fields may appear in any order. In general, each floating field appears 
only once unless the field is a member of a list. In this case, a fixed field in the message indicates the 
number of list entries present.

For a list of possible floating field tag values, see 

.

All request messages that can be sent to the CTI Server contain a field called the InvokeID. The InvokeID 
value is returned in the corresponding response message to the CTI client. A CTI client usually places a 
value in this field that enables it to associate a received response with the corresponding request. 
Typically, this is simply a counter that is incremented as each request message is sent.

The C

ISCO

 CTI Interface presents Call Event data using a CSTA-like model; however, the underlying 

ACD datalink may or may not conform to this model. This means that, depending upon the type of ACD 
being used, some Call Event messages may not be generated, and some of the CSTA message data for 
other events may not be available. Be aware that the interpretation of Call Event data is very 
peripheral-specific, particularly when multiple ACD types are being used.

For a discussion of peripheral-specific considerations, see the 

The Call Event messages detailed later in this document typically provide several different device ID 
fields. Depending upon the type of peripheral and the nature of the event, the device ID may represent a 
Trunk number, a Trunk Group number, or an agent teleset number (extension). Some peripheral types 
may not provide a device ID for one or more fields. To handle these situations, the Call Event messages 
provide device IDs using two fields: a fixed field indicating whether or not the device ID was provided 
and enumerating the type of device identified, and a floating field containing the device ID (if provided).

The Call Event messages also provide a list of CTI clients associated with the current call (if any). This 
information is provided using a separate floating field for each CTI client in the list, and a fixed field 
providing a count of the number of entries in the list. Each list entry’s floating field uses the same tag 
value.
