[solved]Disconnect caller alone-Conference

Hi

Currently I have a caller that calls to an IVR and the Ivr patches him to the “called” and a conference is established.
So after gour minutes into the conference I want to disconnect the caller alone, but I want the “called” to stay in conference.
Is this possible, and how?

Iam using meetme application for conference

I would experiment with interposing a local channel and putting a time limit on the Dial for the local channel.
