PeriWeb
PeriWeb is used to both build new applications to take advantage of the Web, and also
extend existing IVR applications to the Internet user community. While IVR
applications use the telephone as the primary input/output device, World Wide Web
(WWW) browsers can provide an alternate visual interface for many types of
transaction oriented applications. PeriWeb software facilitates this access mode with
minimum changes. A user of a WWW browser initiates a “call” to an application by
clicking a hypertext link. PeriWeb “answers” the call and routes it to the proper
application. The application normally responds with a request to generate a greeting,
but PeriWeb translates this into a dynamic hypertext document and sends it to the
browser (caller). The user enters responses through forms or image maps, and
PeriWeb delivers these responses back to the application.
Standard PeriPro IVR applications connect callers to MPS systems, where recorded
voice prompts guide them to make service selections and enter information using
touch tones or spoken words. The MPS responds to the caller using recorded prompts,
generated speech, or fax output, as appropriate. For existing Avaya customers with
IVR applications, PeriWeb software provides Internet access with minimal changes to
the application programs. This leverages existing investment in application logic and
host/database connectivity and transaction processing.
For customers with existing PeriProducer applications, PeriWeb adds:
• access to the World Wide Web
• an environment that does not require application logic changes for access to
basic features (that is, IVR supported interactive transactions using a Web
browser)
• enhanced Web presentation without changes to application logic and
processing
In summary, its features allow PeriWeb to:
• co-exist with standard WWW servers, such as HTTPD, but does not rely upon
them
• incorporate network-level security based on WWW encryption and
authentication standards
• support standard HTML tagging formats created with a text editor or Web
publishing tool
• perform Web transactions directly from the internet or through a relay server
• support the Keep-Alive feature of the HTTP1.1 protocol
• support the PUT method for publishing new HTML pages
• support standard and extended log file generation
• enable Web-aware applications for enhanced presentation on the World Wide
Web using Web-oriented features
• support multiple languages for interaction content
• support Java based applications for browsers with Java capability
