ConfBridge issues

Hi all,

I have upgraded to the 1.6.2.0 version of Asterisk and set up a conference bridge using the ConfBridge() application. For the most part, it works great. The problem I have is when there are more than 2 people in the conference, and one of them hangs up, everyone left on the conference hears a busy signal.

Has anyone else seen this? Any suggestions on how to get around the issue?
