Conference Trigger


I have tried the scheduled conference feature - with conference invites - and it works great!
I would, however, really like to have this exact feature with a different trigger. I would like the trigger to be a DID or extension number - that when dialed, will trigger off the conference invites.

I keep thinking there is some workaround that I can make this happen, but I still haven’t found it. If anyone could offer assistance, it would be helpful.
