Optional components include:

- **[License Proxy Server](/guides/self-hosted-add-ons-license-proxy)**: Serves as an intermediary between our hosted license server and your self-hosted deployment. We recommend installing this component to ensure constant uptime for request authorizations.

- **SIPREC**: For customers who would prefer to use Deepgram's real-time transcription on a traditional telephony stack rather than with websockets, Deepgram offers a native SIPREC integration solution.

- **[UniMRCP Plugin](/guides/self-hosted-add-ons-deepgram-unimrcp-plugin)**: Offers speech recognition for cross-platform MRCP services.
