Modem to modem using TDM400P card

Asterisk Asterisk Hardware

The goal is to make hardware modem to hardware modem calls. I have installed a TDM400P card on my PC, which is running Elastix 2.4 . The card has one FXS and one FXO port, which are detected by Elastix. One extension has been created. Looking for suggestions on what additional configuration must be done.

TIA Robert

The Elastix distribution is dead and no longer maintained.

If you wish to use a GUI I’d recommend FreePBX which has an active support community at https://community.frepbx.org
