Thanks to Touch Tone Tommy's suggestions I have got it working. I actually just copied the settings from a working extension. I did the #505 command at the same time, though. It was one of those things that fixed it!

BTW hitechcomm, I have used the services of other users here in the past. Its how I became even remotely familiar with these systems and why I posted here again.

No thanks to hbiss for his unhelpful and condescending comments.
