Can anyone please help?? I am having a hard time with a Digium TE133 T1 card configured in Freepbx. I just installed the system and configured everything through the web interface, everything seems right, I can make and receive calls except that there is a lot of static on the calls. I notice this on the logs as well.

Looking for support in Digium they recommedn to disable the Linux Framebuffer as It can cause these type of problems with the cards. They recommend to modify /boot/grub/menu.lst. However I am not sure how to do that. The examples thay give don´t match with what there is on this file
grub.conf generated by anaconda
Note that you do not have to rerun grub after making changes to this file

I assume that putting default=0 instead of 1 would disable it but I am not sure. My system is already in production and I don’t want to crash it.
Here is my system.conf
Here is my chan_dahdi.conf
; for user additions not provided by module
; include dahdi groups defined by DAHDI module of FreePBX
; include dahdi extensions defined in FreePBX
here is my chan_dahdi_groups.conf
Thnaks a lot
