Highlander The immortal conference ... how will I cut her head !?

From time to time I use conferences with some customers

The fact is that mysteriously for freepbx the last to leave the conference is as if it remained inside the conference even though it put down …

I attach AMI report:

Action: ConfbridgeList
Conference: 800

Response: Success
EventList: start
Message: Confbridge user list will follow

Event: ConfbridgeList
Conference: 800
CallerIDNum: 13
CallerIDName: Sara

Admin: No
MarkedUser: No
WaitMarked: No
EndMarked: No
Waiting: No
Muted: No
AnsweredTime: 4855

Event: ConfbridgeListComplete
EventList: Complete
ListItems: 1

At this time understand why it would be nice

However I would like to find the AMI or AGI command to close the conference …

I tried it so, she answered that it closed but then it remains open …

Action: Hangup
Channel: Local/[email protected];2

Response: Success
Message: Channel Hungup

What a strange thing

I tried it at the command line … you will not believe it but you still have to wait for the conference !!!
