## Account Number

## Definition

An account number is an information that the extension user can add to each call in order to classify it for a postprocess in conjunction with a Call Information Logging (CIL)-unit.

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

Account numbers can be made mandatory for calls to selected trunks from groups of extensions as well as verified according their validity.

## Use

An account number can be utilised in all external traffic scenarios (outgoing and incoming) for which it is desired to debit the call information (in the most cases the costs are used) to different accounts.

Typical applications for account codes are:

- Lawyer‘s office where costs are to be debited to the accounts of the various clients.
- Student‘s residence where several students are sharing a common extension
- Travel agency where it is required to register different types of orders and inquiries.

It is possible to make an account number mandatory, which means that the user must dial an account number in order to get access to external lines.

The verification of an account number prevents typing faults and and also the creation of new undefined account numbers. The user can only access the external line when an account code is entered which is specified in the system (list of 1000 account codes).

Note

When the feature account number is activated, no external call can be initiated without entering an account code. In order to disable this functions for emergency calls, dedicated emergency trunk routes and a dedicated trunk have to be reserved for this purpose. See Programming example for emergency calls without account code

## 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) record.

Otherwise the user will be informed by a congestion tone that the external call is not allowed. 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.

#### DBC 210, DBC 220, DBC 211, DBC 222, DBC 212, DBC 631, DBC 223, DBC 213, DBC 662, DBC 224, DBC 214 and DBC 663 Telephones

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 224, DBC 214, DBC 663), 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

2114 |  | Valid Account Codes

A table of verified account numbers, which allows the entry of up to 1000 entries, will be displayed with this command code. If an entered account number already exists, an error box will be displayed. This command will support adding, deleting and altering of account codes.

### Programming example for emergency calls without account code

Objective: In order to initiate external calls, the users always shall enter an account code, however the international emgercency number 112 shall always be dialable without entering an account code and without entering a route number.

1. Define a trunk route with the directory number 11

5401 |  | Create Trunk Route

1. Assign a trunk directory number, which does not require an account code, as a member to this route.

3201 |  | Route Members

Note

By using this programming, the trunk line is the reserved for outgoing emergency calls only. In order to garantee that this line will not be occupied for incoming traffic, it is recommended to use a trunk number which is not included in the public number series of the company.

1. Define predigits for this route, which shall be dialled out in front of each external dialled number. In our case it is “11”.

3303 |  | Predigits

Note

This programming prevents a missuse of the trunk route for other purposes, as the number 11 will always be inserted in the dialled number.

If the users are dialling the number 112 directly, the trunk route 11 selects the desired trunk line. The number 11 will be inserted as predigits in front of the last dialled digit 2, in order to send out the number 112 to the public network.

## Equipment
