[asterisk-users] Problems with Dahdi 2.3.0.1 trying to load OSLEC

[Jose P. Espinal]

Hi Tzafrir,

Maybe I did not understand very well your answer, but just in case, 
doing a 'locate dahdi_echocan*' on the Asterisk box, gives me the 
following output:

...
root at slackbox:~# locate dahdi_echocan*
/lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_kb1.ko
/lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_mg2.ko
/lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_sec2.ko
/lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_oslec.ko
/lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_sec.ko
/lib/modules/2.6.29.6-smp/dahdi/dahdi_echocan_jpah.ko
...

Is there something I should change/add somewhere before/post compiling?

The documentation on the OSLEC website does not give deeper details 
about this. Any idea where else should I looK?
