MTP3 API Configuration

The configuration files involved are:

wanpipeN.conf
Provides configuration parameters for Wanpipe Drivers.
freetdm.conf
Provides I/O configuration parameters to FreeTDM.
freetdm.conf.xml
Provides signalling configuration parameters to FreeTDM.

Sample LSL configuration file
Sample HSL configuration file

freetdm.conf

The freetdm.conf configuration file is located in /usr/local/freetdm (default). It contains I/O specific parameters.

General Format:

[span wanpipe <span name>]
d-channel => <span number>:<channels>

freetdm.conf.xml

The freetdm.conf.xml file is used by the sample application to generate span configuration parameters. The parameters are then passed to the FreeTDM library. The freetdm.conf.xml can be located in any directory, it is specified as an argument when running the sample application.
