BusinessPhone – Premium Telephone
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
