After installing the card in the system and run the installation program for the first time, the drivers and Khomp services will be added at system startup, and automatically loaded.

If your system has at least one E1 trunk card and / or an FXO card, a basic setup screen will be presented at the end of the process, questioning signaling parameters - if there are signs E1 - and/or performing the adjustment cadences - where that FXO cards.

If all these steps were performed successfully, proceed to the item Using Khomp Endpoint. If a problem occurs, see the User Guide, in the section Troubleshooting.

Using the Khomp Endpoint

After installation and startup services required by Khomp, FreeSWITCH can now be loaded or initialized.

Use the -nort may result in loss of audio quality, causing a serious commitment on the progress of system connections.

After initialization of FreeSWITCH, you can verify that the module was loaded Khomp through the following command:

freeswitch@hostname> module_exists mod_khomp

The next line should answer something like:


To verify that the FreeSWITCH recognize all the cards, type:

freeswitch@hostname> khomp summary

The output of this command will show details of all cards accepted.

In the case of an E1 card, you can check the status of links with the following command:

freeswitch@hostname> khomp show links

The state of individual channels, in turn, can be measured with the command:

freeswitch@hostname> khomp show channels
