you could use the db app to hold state across multiple calls... maybe 
use the ${caller_id_number} and the ${destination_number} as keys for 
the insert/select so that there's something constant to use in the 
select... and another extension or two may be needed...

You could do the db lookup before you make the call so that you see if 
your caller is already a member of a conference.... if he is, then the 
transfer from *1 would work much the same as it does now except you'd 
use the result of the db lookup as the conference number... if he's not 
a member of an existing conference, then you could generate the uuid 
like Anthony said before, then do a db insert for ${caller_id_number} 
and ${destination_number} to insert that newly created uuid and use it 
as the conference number.... one caveat that i see here is that the 
destination_number would have to be exactly the same as if that user 
were callling and it was his caller_id_number, otherwise your query will 
fail.

you'll also need to "clean" the db when you hangup, which should be able 
to be accomplished with an execute_on_hangup that does a delete of the 
conf data for each user
