You are incorrect.
My x100p clone cards have worked every time they were installed and configure correctly. The issue is apparently unique to FreePBX. they work in Elastix and Vanilla Asterisk just fine. There is a detection utility you need to run . I do not remember the name at present. (if cards are not detected you need to run this utility that FreePBX advises you against using)
They also worked and were detected in the last FreePBX (SCMZ 6.6 Asterisk 11) that I installed 2 days ago. I did install FreePBX with the FXO card already installed.
Dicko if you have not run them nor use them stop trying to be "the expert", what a dicko
