FreeSWITCH Configuration

To configure your system, you will need the following 3 steps:

1. Configure Wanpipe and mod_freetdm
2. Configure FreeSWITCH and mod_freetdm
3. Some Dialplan examples
4. Sangoma ISDN Configuration Options
5. Analog Configuration Options
6. Configuration Appendix

Configure Wanpipe and Freeswitch

The wancfg_fs utility will auto-detect and configure Sangoma hardware, wanpipe drivers as well as PRI, BRI or Analog protocols for FreeSwitch.

#> /usr/sbin/wancfg_fs

The wancfg_fs will create:
# wanpipe config file per physical hw port
-> /etc/wanpipe/wanpipe#.conf                              
# FreeSwitch FreeTDM config file
-> /usr/local/freeswitch/conf/freetdm.conf           
# FreeSwtich mod_freetdm config file
-> /usr/local/freeswtich/conf/autoload_configs/freetdm.conf.xml  

Configure FreeSwitch

To make use of FreeTDM in FreeSwitch we need to enable it in modules.conf.xml located at  /usr/local/freeswitch/conf/autoload_configs/.

Edit /usr/local/freeswitch/conf/conf/autoload_configs/modules.conf.xml and un-comment mod_freetdm line:

Change the following line

    <!-- <load module="mod_freetdm"/> -->

to look like this:

    <load module="mod_freetdm"/>

Some Dialplan Examples

Dial string is:

1. To dial to a specific span:
   "freetdm/<span_name>/a/<destination_number>"
2. To dial to a specific group:
   "freetdm/<group_name>/a/<destination_number>"

Note: If you have a span and a group with the same name, the span will be used.

For example: Following Dialplan calls Sangoma's Toll Free Number when 333 is dialed from SIP phone.
