Does asterisk manager actually work?

We can’t get any return codes from asterisk manager that make sense. Is anyone actually using it successfully?

I’ve actually started development on a Windows-based HUD written entirely through the AMI, and haven’t had any problems with the features I’ve implemented thus far (drag&drop transfering, calling, parking, etc).

I’m having the exact same issues, I telnet to the server and it is not responding to any commands…
