Please give us any clue about this weird case:
We are trying to move a analog card with 20 fxs ports and 4 fxo ports from generic (clone) computer to an IBM X3500 server.
Our problem is the card doesn’t generate dial tone to the analog extensions, despite zttool shows the card OK.
It seems is a power issue, however we’re not sure why, because the power cord has 5.5 volts and seems to be working properly, because the same cord can be used to power a cd unit.
At the generic computer, the card works fine.
Thanks in advance for any tip.
