Input-Control Properties

Platform SDK: Web Telephony Engine

Input-Control Properties

Web telephony maintains a set of parameters that control how the application behaves while collecting input from the caller. These parameters determine the length of time that the application waits for the caller to respond, the page to navigate to when the caller makes too many mistakes, the string that signals the end of the caller's input, and so forth. A Web telephony application can use the input-control properties of the WTEApplication object to change the way the application behaves while collecting caller input. The following table lists and describes the input-control properties.

Property	Description
FirstTimeoutInterval	Interval of time available for a caller to enter a choice after listening to the announcements of menus or controls.
InterTimeoutInterval	Interval of time between consecutive digits of multiple-digit access keys, and between consecutive digits of input for a text control or a text area. In all other cases, the time-out interval is defined by the FirstTimeoutInterval property.
InputTerminator	Termination string for caller input into a text-entry field, a text area, or multiple-selection menu. This string also designates the end of a record operation.
MaxRetries	Number of times the WTE performs default error-handling actions because of a caller's mistakes before dropping the call or navigating to the page specified by the RecurringErrorPage property. Mistakes include pressing a non-valid key or the occurrence of a time-out.
RecurringErrorPage	Page that the WTE renders when the number of consecutive caller errors exceeds the value of the MaxRetries property.
IgnoreNavigationKeysTillTermination	Flag that determines whether Web telephony ignores all navigation keys (those defined by the BackKey, OperatorKey, and HomeKey properties) while receiving caller input for a text control or text area.
InputWaveFormat	Wave format of recorded files, or wave format to be used for SR.
RecordStopSilenceTime	Duration of silence after which recording stops.
MaxRecordTime	Maximum duration of a recorded message.
DetectABCD	Flag indicating whether to detect the A, B, C, and D keys as Dual Tone Multi-Frequency (DTMF) signals (for European countries).
