SpeakRight catches the disconnect event (usually connection.disconnect) in order to do a final postback. This results in the DISCONNECT event being thrown and onDisconnect being invoked. SRApp provides a default handler for this.
There are a number of call control flow objects.
This flow object plays a final prompt and hangs up.
This flow object transfers the call using one of the VoiceXML 2.1 transfer types: Blind, Bridged, or Consultation. The specified destination parameter is a string, such as
"tel:+2560001112222"The format of the dial string is often platform specific.
TransferFlow has two prompts. An initial prompt called main is played before the transfer is initiated. A transferFailed prompt is played if the transfer fails to complete. Both these prompts can be overriden in an app-specific prompt XML file.
If the transfer fails because, for example, the destination is busy, then onTransferFailed is invoked. It plays the transferFailed prompt. Or you can override onTransferFailed and provide your own behaviour.
This flow object is a low-level object. We recommend the use of SROTransferCall instead.
This flow object is an escape hatch. The application can supply any VoiceXML it likes. RawContentFlow may be useful for invoking platform-specific call control features.
