[Freeswitch-users] Best way to create a one to many 'broadcast'

Hi, I would like to use freeswitch to host a one to many broadcast style conference call. The challenge I have is that there won't always be any listeners so the conference application isn't quite working for me. Essentially, the speaker dials in with something important to say, by default the system will simply record what they say as an archived message and then they hang up. This works fine but I would like to extend the functionality so that other people dialling in have the option to connect into this call and listen to the message live. Can you advise me on the best way of achieving this: conference, bridge, eavesdrop or something else? Many thanks Andy
