Hi Francois, Thank you for your interest. I tried the card alone so I don't think is an IRQ problem (anyway is there a way to be sure?) To be sincere, in all systems I saw (even working ones) there is an IRQ balance failed where Linux boots. The system is new, I tried different processors (P4 and Celeron) with SMP kernel and without. The card has the echo module, could not be this module the problem? I need to set up in any way asterisk to use it correctly? Since now I leaved the echocancel = yes in Zapata.conf, is this correct? Or as it is hardware it must be echocancel = off in the software? (Any way I tried to put it off and there is echo! ;) RAM: 1 GB (and Munin is telling that I'm using 256 MB). I compiled many different version of ZAPTEL and I tried different Asterisk versions. Hope to had give you more info.

Eg. on one of my boxes with a TDM400P: CPU0 0: 1231472788 XT-PIC timer 2: 0 XT-PIC cascade 5: 0 XT-PIC uhci_hcd:usb1, uhci_hcd:usb2 7: 1 XT-PIC acpi 8: 4 XT-PIC rtc 11: 3101088 XT-PIC eth0 12: 1231265328 XT-PIC wctdm 14: 43803 XT-PIC ide0 15: 66249 XT-PIC ide1 NMI: 0 LOC: 0 ERR: 0 MIS: 0 This isn't foolproof, but it's a good start. (and I don't know of the wctdm module is the same on the TDM2400P card though) You can also check that the card isn't losing interrupts by running the zttest proram: /sbin/zttest wait a few moments then kill it with Control-C - Eg. --- Results after 46 passes --- Best: 100.000000 -- Worst: 99.987793 -- Average: 99.993896 There's more on interrupts here: http://www.voip-info.org/wiki/view/Asterisk+PCI+bus+Troubleshooting It's aimes at the TDM400P card, but I'd be surprised if the 2400P is that much different (but someone please correct me if it is!)

Uhm. Actually if I write: cat /proc/interrupts I get: 11: 2997154835 XT-PIC libata, wctdm24xxp Is this the problem? How can I solve it? The output of zztest is: [root@asterisk1 freepbx-2.2.0]# zttest Opened pseudo zap interface, measuring accuracy... 100.000000% 100.000000% 99.987793% 100.000000% 100.000000% --- Results after 5 passes --- Best: 100.000000 -- Worst: 99.987793 -- Average: 99.997559 Thank you very much indeed!
