I posed this question to Digium months ago. They recommended not using
any more than 3 TDM cards per machine. I suspect IRQ conflicts are
probably the main issue. I can't get more than 2 working in an IBM X345
server at the moment. Trying to initialize the driver with the 3rd card
installed causes the machine to reboot.
Moving forward I will look at channel banks for anything requiring any
more than 8 fxo ports. Feel free to contact me off list if you want to
discuss further.
