# Voicemail Service

VoiceMailMenu implements a top level voicemail service. 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://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/api/telephony-application/README.md).

### 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?)**

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://prosbcdocs.telcobridges.com/telecom-references/telecom-concepts/voicemail-service.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
