I'm not sure what you mean, I had one card with one FXO in it and it worked fine. Now, we have 2 TDM400P cards with all of their slots filled with FOX chips and I can't make out going calls. Those are the only 2 cards on the system, the rest is just motherboard. -----Original Message----- Do you have ATI FXO daughter cards. We had experienced similar problems. After replacing the ATI with Digium X100M Rev B daughter cards the system has been running fine. -------------- next part -------------- An HTML attachment was scrubbed...
