MRCPv1 Server Parameters

Reference Number: AA-01106 Views: 2928 0 Rating/ Voters

The following server options are controlled via the mrcp.config file, located in the config directory of the MRCPv1 installation folder. By default, this location is C:\Program Files\Lumenvox\MRCPServer\config\

See Configuring Parameters for more information about changing various MRCPv1 parameters.

enable_logging

This parameter enables or disables MRCP logging. Possible values are either 0 (no logging) or 1 (logging enabled).

Default: 0

mrcp_server_log

This parameter may be used to specify a custom logfile name for the MRCP Server log. The logfile is created in the directory where the MRCP server is started. This is usually the bin folder under the Engine installation directory.

Default: MRCP_Log.txt

mrcp_server_ip

The IP address of the machine running the MRCP server. This must be set.

Default: 127.0.0.1

mrcp_server_port

This TCP port on which the server will listen for incoming RTSP requests.

Default: 554

mrcp_server_rtpbase

The lowest numbered UDP port that will be used for RTP and RTCP. Two sequentially numbered ports will be used per resource, one for RTP and the next for RTCP. This parameter must be an even number.

Default: 49638

mrcp_server_connmax

The maximum number of concurrent connections. It cannot be more than the number of resources available. There needs to be at least one resource per connection.

Default: 100

mrcp_server_resmax

The maximum number of concurrent resources. Practically speaking, this number cannot be greater than the number of port licenses you have for the Speech Engine.

Default: 100

sre_ip

The IP address of the machine running the Speech Engine. You may specify multiple speech servers by providing multiple IP addresses separated by semicolons.

Default: 127.0.0.1

sess_timeout_sec

MRCP sessions timeout after a period of inactivity. This parameter specifies the length of that period, in milliseconds. During a session, if no further requests are received for the time specified in this parameter, the session will timeout.

Default: 20000ms

enable_sre_logging

The LumenVox Speech Engine can save response files (files with the extension .callsre) that contain data about each interaction, including recognition results and audio. This parameter, which can be set to 0 (off) or 1 (on), determines whether those files are created.

Default : 0

resource_string

A string that will be used to identify the recognizer resource when the MRCP client begins a session. For example, by default a client would ask for the URI rtsp://127.0.0.1/recognizer in order to get the resource, as the resource_string defaults to recognizer. If you change this, you must ensure that your client is using the same identifier.

Default: recognizer
