Create conferences manually?

Is there any way to create a conference manually ?
For example : I request user to input conference_No and conference_Password. And then, I create a conference with those aguments so that only ones who know the conference_No and conference_Password can join the conference.

core show application meetme

and pay particular attention to the ‘D’ flag - you’ll have to write a little IVR to capture the desired conference number and PIN and pass it along to MeetMe() to create the conf. And of course you’ll have to give a way for others to be able to enter these conferences (use a steering digit or some other detectable pattern, or write another IVR to allow people to type in the conf number)
