Hi list, i'm having a problem with asterisk+pstn termination, i just bought a TDM400p and connect my phone line(bellsouth) now when im using the pstn through asterisk there's an echo, i don't know if this is already have been resolved. If it does please point me to the instruction how to resolve this.

Try reading README.fxotune and using fxotune to see if it improves it. Also make sure that you're using the latest version of zaptel (with the KB1 echo canceler). If that still gives you echo, try using the patch for bug 5520 and change your echo canceler to that to see if it improves your echo.
