Configuring Media Server Parameters

To change the Media Server configuration settings, edit the media_server.conf file found in mrcp-api/docker/lumenvox/ for Docker-based MRCP installations.

The values specified in this file will be used by the Media Server when it is first started and will apply to all recognitions unless overwritten as part of the MRCP request. All of the Media Server Specific Parameters must be set in the configuration file and cannot be modified without restarting the server.

The MRCPv2 specification allows for MRCP sessions to include, as part of a RECOGNIZE or SET-PARAMS method, changes to MRCP parameters that apply to that session. The parameters that are part of the standard are outlined in the Streaming Media Properties article and may be set either via the configuration file or as part of the session.

The platform also extends the MRCPv2 specification with a number of vendor-specific parameters. Like the standard parameters, these can be set in either the configuration file or as part of a RECOGNIZE or SET-PARAMS method. These vendor-specific parameters are documented in the Vendor-Specific Parameters article.

If you are used to working with VoiceXML (VXML) or the Speech Engine API, see the article on how various VXML/API properties correspond with MRCP properties.
