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 87.
