Conference Bridge with same number?

I was able to set a conference bridge, however I am having difficulties in meeting my requirements.
as of now I have to use two different DID’s
one DID for the users to join a conference + another DID for the admin to start a conference, both users are configured with a PIN before access the conference. this setup works fine.

however. I want to use a single DID
and based on the pin, to allow the access either as administrator starting the conference or as a user joining the conference, can this be done ? if so, can you pls share a guide.

Thank you

Answer the call and then use the Read() Application to accept input from your users.

Then based on that input enter the conference room as a normal user or an Admin.
