Blast call in Conference

I need to make blast call during conference. Suppose a person initiates a conference and gradually adds other people in this conference. When a new person is invited in the conference, 3/4 of the called person’s phones needs to be ringed and if he pick up one phone, other phones will hang up and the called person will be attached to the conference.

I know that blast call can be made using DIAL application. How can I achieve the same functionality for MeetMe application?

Thank You.
