Hi,

My wildcard TDM 400P's FXS port(connexts to a analog phone) has ticking
noise recently.
Dialing completlyfails because of this.The only thing still working is
generating rings when
being dialed.

I have followed http://www.voip-info.org/wiki-Asterisk+Hardware .
and make sure wctdm is not shareing interrupt with any other devices.
I even run " /sbin/hdparm -u1 /dev/hda1" to avoid harddisk interference.
But the ticking is still there, what could cause the problem?

I am so frustrated, please help.

[root at mjia zaptel]# cat /proc/interrupts
