In the flow diagrams shown in this chapter (for example, Figure 10), vertical dotted lines indicate the components involved in the exchange of information between systems. The horizontal arrows indicate the direction of the flow for that step. The numbers lined up on the left side of the flow are reference points to the flow and indicate the progression of the calls made on the conversation. These same numbers correspond to the numbers under the Step heading of the text description for each example.
The call parameter lists shown in the flows are not complete; only the parameters of particular interest to the flows being discussed are shown. A complete description of each CPI Communications call and the required parameters can be found in Chapter 4. "Call Reference".
A complete discussion of all possible timing scenarios is beyond the scope of the chapter. Where appropriate, such discussion is provided in the individual call descriptions in Chapter 4. "Call Reference".
Note: The softcopy versions of the flow diagrams in this chapter may not display all characters that appear in the printed book. For example, arrows are shown as dashes on some display devices.
