I'm using a Digium TE412P card.

I turn off echo cancelation without result.

So i try to unload the modules wct4xxp and zaptel and it's running now.

I try with echo cancelation and it's working.

I don't know why the reloading of modules make asterisk working.

Have you ever meet this situation ?
