Account number
An account number can be entered to debit telephone costs to
different accounts. Depending on the system configuration the
account number has to be entered from a verified account number
list (predefined) or you can invent an own account number. The
following prerequisites apply:
With the verified account number you can restrict the making of
external calls (not a specific number or area), so everyone who
is allowed to make external calls will receive an account number
which has to be used each time he/she wants to make an
external call.
Verified account numbers contain up to 10 digits.
Own account numbers contain up to 15 digits.
The account numbers can also be used via the DISA function, see
section Direct Inward System Access (DISA) on page 55.
