# Defining the Video Messaging Server configuration

The ADI service and the MSPP service provide the flexibility to satisfy the following requirements:

- Selected audio codec types for the network and for storage

- Optimized for audio quality and board resources by allowing applications to audio transcode only when necessary

- Audio silence detection

Note: Video path is always configured in pass-through mode because the Video Messaging Server Interface does not provide video transcoding capability. This configuration requires no DSP resources on the CG board, and is the same for all audio configurations.
