How to Originate call to all queue member ? (using AMI)


I’m looking for a way to play a message to all member of a queue.
So I’ve tried the following:

Action: Originate
Application: Playback
data: tt-somethingwrong
Channel: :question:
Timeout: 20000
CallerID: Message

The problem is that I don’t know how to specify the queue. Using SIP/xxxxx works fine but it only calls one operator…

Any idea ?
