OTRS is a platform independent Web-based help desk system that supports service organization of any kind (e.g. IT service, customer and technical product service, complaint management, public services, etc.) to increase their efficiency. It increases transparency as well as service quality and lowers your total cost of ownership. It has been certified ITIL V3 compatible by PinkVERIFY for incident, problem, change, service asset and configuration, request fulfillment, and knowledge management. Other ITIL processes like service catalog and service level management are supported as well.
VoiceXML::Client is a library that provides Perl programs with the ability to act as a user agent that fetches Voice Extensible Markup Language (VoiceXML) documents, parses them, and then executes the instructions therein by playing prompts and collecting user DTMF input/voice recordings through a handle to some type of telephone or other device interface. VoiceXML::Client's focus is on the client side. The XML documents are generated by a distinct process of your choice, unrelated to the library.
