The Plum DEV Reference Manual also references the tags and properties that are used in VoiceXML. You can view descriptions and examples of how the various tags and properties are used. There are also links to other resources such as the VoiceXML specification and specifications for using the syntax of JSGF and SRGS grammars.

The Plum DEV Guide also documents how to use our Outbound API. The Outbound API can be used to place outbound calls for your applications. The Plum DEV Guide also details how to create a call report and provides a debugging guide for developers with tips on how to validate their scripts and how to find and debug errors.
