basic set-up for an Asterisk conference is that anyone who want’s to join to a conference will have to dial a particular number (the conference number) just to join. Now here’s the thing.
Is there a way that the Asterisk user will be the one to call or initiate a conference (call out) so that participants will not dial a number for a meetme room. Of course if you want to form a conference you’re the one to initiate (right?).
