[Asterisk-Users] Will Echo problems EVER be solved, I'm scared

[Alfredo J. Fabretti]

I have several production systems with tdm400p.

Do you have any IRQ conflict? cat /proc/interrupts

Did you try changing the pci slot?

Maybe the fxo module is damaged? did you try changing it to another 
place of the
card? I don't know if this can help, anyone?
