good afternoon, please can you help me? I am installing a TDM400P card with 4 FXO. Elastix is not detected, my question is to the card with no q feed power cable 12? or only when plugged into the PCI port should work.
Since Digium hasn’t manufactured TDM400 cards since 2008, you’re likely installing a clone card. Clone cards are built by people that don’t develop or support Asterisk.
The 12V connector on the TDM400 was necessary to provide ringing voltage for telephones connected to FXS modules. FXO modules do not require the use of the 12V power connector.
