When a caller reaches the system, several services may be offered depending on the calling number, the called number or any other criteria. Such services maybe be conferencing rooms, chat rooms, call-bridging, voicemail, or any other service. Toolpack already provides source code for some reference services such as call-bridging and voicemail. Those services are built upon Toolpack and uses all the building block to provide the service. ### Usage When an incoming call reaches the system, the application chooses the appropriate service for this call leg. Then the application creates the service by instantiating the proper service class, and then assigns the call leg to the service. Here are some reference services provided by Toolpack: * [CallBridging reference service](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/voice-media/bridging-service/README.md) * VoiceMail system reference service *** Return to the Toolpack [User Guide](https://github.com/telcobridges-main/tmedia-wiki/tree/main/tmedia/configuration/user-guide/README.md) --- # Agent Instructions This documentation is published with GitBook.

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/other-pages/services.md?ask=&goal= ``` `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.
