Any system configuration is typically best built from the bottom up. This means starting with configuring the lower layers and moving your way up as you go. In order to interface with FreeTDM from FreeSWITCH you must configure several different components:

  • Hardware devices (for example, Wanpipe or DAHDI configuration)

  • The FreeTDM library

  • The FreeSWITCH mod_freetdm endpoint configuration

Wanpipe

You can then start each device with wanrouter start. This starts all devices and populates /dev/wanpipe/ with a device for each channel (for example, for a T1 it will create /dev/wanpipe1_if1 to /dev/wanpipe1_if24). A span and channel number physically identifies each device. This is important to keep in mind, as it...
