I'm running this config with a fritzcard and some mgcp hardphones and it will 
still give me echo on certain occasions:

- Calls between my isdn and a gsm or isdn line are fine
- Calls between my isdn and an analog line gives me echo on my side

Although I've tried many settings to solve this properly I have not succeeded 
in it. My hopes are now focussed at the ZapBRI stuff, since it can use the 
zaptel echocancellers (I think).

Best regards,
Florian
