'@channels'?

What is the Dial command you use?

Can you post the relevant part of your diaplan?

Also, try:

  bri debug span 1

And see if you see any traffic there when you try to call out.

In addition: are you sure that there are channels set for group=0 ?
Maybe try a channel directly: Zap/1 or Zap/2 instead of Zap/g0 .
