A-number is displayed. 32 different public numbers can
be assigned to the trunks. Up to 16 digits can be
programmed per public number.
Limitations
For MFC only the A-number of the calling party will be
send out. In case of an incoming call the number of the
connected party will not be sent out.
To program a public directory number only digits 0 - 9

The accumulated costs for each call will be assigned
to the entered extension number.
