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
