I would like to thank everyone for the opinions. I will consider all of that

This sounds like a desire to have the conference mixer do something 
special. As such, something around mediactl might be appropriate.

Or, it might be viewed as introducing another sort of participant into 
the conference. Perhaps this could be done by sending a REFER to the 
focus, with a URL for the resource in the Refer-To header.
