Account Number

An Account Number can be entered to debit telephone cost 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 your 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 and can only 

be used before you make a call (outgoing external calls). 

•

Own Account Numbers contain up to 15 digits and can be used 

before or during the call (outgoing external calls).

The Account Numbers can also be used via the DISA function, see 

section “
