Handling key input from callers Blueworx Voice Response supports up to 16 keys on the telephone keypad: A, B, C, and D in addition to the twelve normal keys (1 through 9, *, 0, and #). Callers can press single keys (for example, to select options) or multiple keys (to enter data such as personal identification numbers).
Handling spoken input from callers Speech recognition means that you can write voice applications that take action based on spoken input from the caller.
Telephony activity How Blueworx Voice Response interacts with the telephony network.
Designing voice messaging applications You can create your own voice messaging applications or add voice messaging to existing applications. For example, in an ordering application, you may choose to let people leave a voice message to be associated with an order. This is known as transaction-related voice messaging.
Managing voice messaging resources This section describes how to create and maintain mailboxes, subscriber classes and distribution lists for use by a voice messaging application. Messages occupy disk space, and disk space usage must be monitored.
Telecommunications Devices for the Deaf The Telecommunications Device for the Deaf (TDD) is a telephony device with a QWERTY keyboard and a small display and, optionally, a printer. Instead of speaking into a mouthpiece, the caller types messages on the keyboard; instead of hearing a voice from the receiver, the caller views the messages on the screen, and can print them for later reading. Usually, at both ends of the conversation, TDDs are being used.
Background music Blueworx Voice Response includes a background music subsystem called the juke box, which you can use to play background music in your applications. This section tells you how to implement background music using the juke box:
TDM connection management TDM connection management helps to coordinate the making and breaking of time-division multiplex (TDM) connections between resources such as channels on packs, and channels on digital signal processor (DSP) adapters. Custom server subroutines allow you to write applications that exploit industry-standard time-division multiplex (TDM) bus (TDM bus) capabilities such as matrix switching, one-call fax, speech recognition, and text-to-speech.
Designing for a single system image Most voice applications will run without any changes on Blueworx Voice Response systems that are configured as a single system image. State tables, prompts, or custom servers that use application data (by, for example, playing or recording voice segments) do not need to be aware of whether or not they are running on a single system image: they will access that data in exactly the same way whether they are running on a stand-alone Blueworx Voice Response system, on a client node, or on a database server node. However, you should consider the following points when you design a voice application that will be run on a single system image:
Using ISDN call transfer This section describes how to transfer calls on Blueworx Voice Response using ISDN. Blueworx Voice Response supports four protocols, EuroISDN and E1 QSIG Single Step Transfer Supplementary Service protocols, the ISDN two B-channel transfer protocol, and the Nortel proprietary Release Link Trunk (RLT) call transfer protocol.
