This class shows how easy it is to use the ToolPack’s IVR classes. This service demonstrates a simple Voicemail service, which can be used in the two following scenarios: * Directly on an incoming call Leg * From a user defined state during a call (i.e., busy or no-answer). Class TBCAF::CTBCAFVoiceMailMenu|CTBCAFVoiceMailMenu shows how to use the ToolPack’ IVR classes to build a full featured IVR Application. ### Usage VoiceMailMenu can be used directly on the ITBCMCLib::OnCallLegPresent() Event. This class can be used like CTBCAFBridgecall **(LINK?)** bridging class. The usage is the same, but the service differs. Moreover, VoiceMailMenu can be used from any moment during a call, on a user defined event like busy or no-answer. This service is used by the [Telephony Application](https://tmediadocs.telcobridges.com/telecom-references/developer-reference/caf/telephony-application). ### Caveats This is a demonstration service, and as such it cannot be used 'as is' nor derived from. ### Classes * TBCAF::CTBCAFIvr|IVR Menu manager * Interface of Menus handled by the Menu manager **(LINK?)** *** Return to the Toolpack [User Guide](/other-pages/getting-around-the-portal/user-guide.md) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` GET https://tmediadocs.telcobridges.com/products/tmedia/features-and-solutions/solutions/voicemail-service.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
