Turned disconnect supervision on, and all appears to be well now. Thank you so much. I have had other problems in the past that I had no explanation for that I think will also be cured because of this.
The problem I have had in the past was our secretary would take a call and when she would hang up, her phone would not ring for the next call or two. I figured out that the phone switch was not dissconnecting the line, but I didn't know why.
Thanks guys
Casey
