For TAMTAM CLASSIC each employee calls their own
number which identifies them, from there he/she receives an
answer letting him/her know whether it has been carried out
correctly or not. For TamTam CODE all of the employees phone the
same number, they are then asked to provide a personal
identification, they are then also informed whether it has been
carried out correctly. In this case, the ID recognition can be
carried out through keying in a code on the telephone itself or
via voice recognition. Both systems guarantee the calls are free.
