[Asterisk-Users] (newbie) no dialtone on a TDM400P card

[Thomas Andrews]

I think I know what the problem is. I think that asterisk cannot
generate dialtone because it had a problem with the soundcard.

[chan_oss.so] => (OSS Console Channel Driver)

I had to put this in modules.conf to get rid of the error:
noload => chan_oss.so

So I assume now that it's not capable of making dialtone ?
