Please think logicaly also.Is it possible to make a single call from
different people to different people?
FOr example from your phone at the same time how many persons can make a
call or to how many persons you can make a call.
Even if you are having one URI and numerous contacts, is it possible to make
call to one/more than one person simultaneously from all the contacts.
Obviously no.
rite?
