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 66.
