## Account Number

## Definition

An account number is an information that the extension user initiates for each call. The verified account number is transferred in the call record to a connected Call Information Logging (CIL)-unit.

Verified account numbers can be made mandatory for calls to selected trunks from groups of extensions.

## Use

The verification of an account code makes it possible to control which extension can make external calls by comparing the account code in the entered account code list. (Internal calls and emergency calls will not depend on account code validation).

The account code list comprises a pool of a maximum of 1000 predefined reference account numbers which are defined within the system. A user enters an account number, which is checked and if the number is available, the number will be accepted or not.

A verified account number can be utilised in all activities for which it is desired to debit telephone costs to different accounts.

A typical example is a company of lawyers where costs are to be debited to the accounts of the various clients. If a lawyer wants to make an external outgoing call to a client, he/she has to dial

* 9 * account number #.

The exchange will check whether the account number is contained in the account code list.

If the account number is not specified in the list, no external call is possible. If the account number is specified in the list, the caller will be connected to the external party.

The function can also be used for incoming traffic. For example, a travel agency may register different types of orders and inquiries.

See also facility description Call Information Logging (CIL) Function (140/155 34-ASB 150 02 Uen).

## Operation

A verified account number has to be used out of the pool of account numbers. This pool of account number data includes up to 1000 predefined reference account numbers with a character length of 10 digits each.

By default, the account code list is empty, and a maximum character length of up to 15 digits is used.

If the specified account codes are stored in the list, a maximum character length of up to 10 digits for an account number will be used and the verification will be performed.

This feature checks whether the account number matches with the stored account number list. If the account number is valid, the call will be allowed and the account code is added to the Call Information Logging (CIL) - unit.

Otherwise the user will be informed that the external call is not allowed and a congestion tone is sent to the user. If the pool of account numbers is empty, no verification check will be performed.

If a user has entered an incorrect account number, in case of DISA (Direct Inward System Access), a voice announcement - “The entered account code is invalid” - will be played. If a wrong account number is entered for a second time, the call will be rerouted to the DISA exit position.

If this feature is used during a call (pressing function key “Account Code”, after call set up) no verification of an account number will be performed.

For calls to trunks for which an account number is mandatory the number must always be inserted before the route number. To facilitate the entry of an account number during a call, a programmable key is required for this function.

#### All telephones

In idle state the account number is entered by dialling the number.

* 9 * account number#

The internal dial tone is received as a confirmation, after the extension can dial the route access code and the external subscriber number.

Upon an attempt to dial an external number on a trunk for which an account number is mandatory the congestion tone will be sent.

#### ECONOMYplus -, STANDARD - and EXECUTIVE telephones and OPERATOR CONSOLE

With these telephones an account number can also be entered during a call provided that a key has been programmed for the function.

- Press programmed key
- Dial account number on key set
- Press #-key
  Telephone with display shows dialled digit

Note

if the account number is entered from an OPERATOR console (DBC 214), NO verification will be performed and the account code with 15 digits will be accepted.

## Capacity

Verified account numbers can be entered for outgoing external calls only (also in case of DISA access).

The maximum entries for the pool of valid account numbers is 1000. Account numbers may have 1 - 10 digits and are used to control access to external lines. Valid digits are 0 to 9.

## Limitations

To be able to enter account numbers during calls a programmable key is required for both outgoing and incoming traffic.

## Programming

## Equipment

To benefit from the account number function it is necessary to equip the system for e.g. ERICSSON CALL ACCOUNT MANAGER.

The feature is protected by a basic FECU (KDUBS13013/1 - V5.1 - R13 onwards).
