With a Group Call to a MeetMe-Conference


I want to have the following application:

In my extensions.conf I have a Group Call for clients 31, 32, 33, 34, 35 and 36:
exten => 1,1,Answer()
exten => 1,n,Dial(SIP/31&SIP/32&SIP/33&SIP/34&SIP/35&SIP/36)

Is it possible to acquire with the clients obove to a MeetMe-Conference after ringing for example 8 seconds by each client?

For example: Client 31 call “1”, so it is ringing by the clients 32, 33, 34, 35 and 36. After ringing 8 seconds, all the clients will get into a MeetMe-conference.

That’s the application I want.
