In the above example, if the caller 85337096 called the IPPBX system, IPPBX will disconnect this call and make a
call back to this number using extension 100.
In the call back destination field you can even set the destination to a conference, call queue or DISA, so the
callers can access these functionalities all at the companies expense.
