Examples of value-added services include the following: * [Background music injection](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/concepts/background-music-injection/README.md) * [Conferencing](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/concepts/conferencing/README.md) * [Location-based services (LBS)](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/concepts/location-based-services/README.md) * [Prepaid & postpaid calling](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/concepts/prepaid-and-postpaid-calling/README.md) * [Ringback tones](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/voice-media/ringback-tones/README.md) * [SMS](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/protocols/sms/README.md) * [Unified communications](https://github.com/telcobridges-main/tmedia-wiki/tree/main/reference/misc/unified-communications/README.md) * Voicemail ### TelcoBridges and value-added services TelcoBridges hardware and software products support the development and delivery of value-added services to subscribers. While many of them can be provisioned via the [Tmedia](https://telcobridges.com/media-gateways/products/tmedia-gateways/) family of products, with their on-board application hosts, the [Tdev](https://telcobridges.com/products/development-platforms-tdev/) family of devices, such as the [TMP6400](https://telcobridges.com/products/development-platforms-tdev/tmp6400-tdev-voip-gateway-development-platform/) and the [TMP800](https://telcobridges.com/products/) are the real workhorses when it comes to delivering advanced value-added services that tie together subscriber-specific information, multimedia content and other real-time information. #### Partner case studies * [GlobalRoam and social media applications](https://docs.telcobridges.com/w/images/2/24/GlobalRoam_TelcoBridges_Case_Study.pdf) --- # 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/telecom-concepts/value-added-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.
