Hi Lisa,

I get the following error: DAHDI_ATTACH_ECHOCAN failed on channel 1: Invalid argument (22) when I run: dahdi_cfg -vvvv

Any suggestions?

Hi,
If this, you have not installed oslec or configured successfully. would you please provide SSH to us? And if possible, please add my MSN: This email address is being protected from spambots. You need JavaScript enabled to view it.

Hi,

I sent you the SSH details did you receive them?

I also ran the command as directed, inserting the path to the DAHDI file I downloaded:

sed -i "s|#obj-m += dahdi_echocan_oslec.o|obj-m += dahdi_echocan_oslec.o|" /usr/src/dahdi/dahdi-linux-complete-2.2.0+2.2.0/drivers/dahdi/Kbuild

However I still get the following after running this command:

sed: can't read /usr/src/dahdi/dahdi-linux-complete-2.2.0+2.2.0/drivers/dahdi/Kbuild: No such file or directory

Should there be a folder called KBuild here?

When I run the command:

ls /lib/modules/`uname -r`/dahdi/dahdi_echocan*
/lib/modules/2.6.18-128.1.10.el5/dahdi/dahdi_echocan_jpah.ko /lib/modules/2.6.18-128.1.10.el5/dahdi/dahdi_echocan_sec2.ko
/lib/modules/2.6.18-128.1.10.el5/dahdi/dahdi_echocan_kb1.ko /lib/modules/2.6.18-128.1.10.el5/dahdi/dahdi_echocan_sec.ko
/lib/modules/2.6.18-128.1.10.el5/dahdi/dahdi_echocan_mg2.k

I cannot see the oslec module here

My system.conf file looks

Any help?

HI,
I have send you infomation to your MSN the day before yesterday. I found where you are wrong. You didn't find the right directory of file. For example, when you run this command:
sed -i "s|#obj-m += dahdi_echocan_oslec.o|obj-m += dahdi_echocan_oslec.o|" /usr/src/dahdi/dahdi-linux-complete-2.2.0+2.2.0/drivers/dahdi/Kbuild
you should run it like this:
sed -i "s|#obj-m += dahdi_echocan_oslec.o|obj-m += dahdi_echocan_oslec.o|" /usr/src/dahdi/dahdi-linux-complete-2.2.0+2.2.0/linux/drivers/dahdi/Kbuild
You should change the directory to yours in your system. The other command is the same.
I have change for you. Now you only should do this:
cd /usr/src/dahdi/dahdi-linux-complete-2.2.0+2.2.0/
make
make install
