[asterisk-users] DAHDI and Oslec

[Marco Signorini]

Hi.
I had the same problem in the past and I've found that there was already 
an echo.ko module built in my kernel module folder.
I've renamed it and replaced with the one compiled with dahdi+oslec and 
it started working as expected.

I was on OpenSuse with kernel 2.6.27.56-0.1... it's very old so I can't 
tell you if this is something true for Debian 6.06 too.

Thanks.
Marco Signorini.
