13.4 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.
To use verified or your own Account Numbers, do the following:
1. Dial * 9 *.
2. Enter Account Number and press #. Valid digits 0–9.
3. After the internal dial tone make the external call.

• Lift the handset.
• Press a Line key.
A call is automatically generated to a predefined number (either an extension
number or an external subscriber number).
The only call that can be placed from this type of line is the direct hot-line call.

expensive way to connect an external call.
