[Asterisk-Users] (euro)ISDN: complete silence / can't hear a word.

[Gunther Stammwitz]

Hello,

I just got my isdn-card working together with i4l and asterisk.
Everything seems to be working fine: I can accept calls coming from the
outside and I can dial out. Even setting the msn works like charm but my
problem is that I cannot hear a word. There's complete silence in both
directions.
Any idea what could be the cause?

Thanks for your help,
Gunther

cologne on it(?)]

In this case the call was just 2 seconds caus I hung up - but that doesn't
matter. Even waiting a minute won't help.
