## Fictive Number

## Definition

A fictive number is a directory number that is not connected to a physical position.

## Use

Fictive numbers are used when it is desired to direct calls to a directory number that is not connected to a physical position. The fictive number can then be diverted direct to any internal directory- or CN-number, except abbreviated numbers (short numbers) in order to prevent misuse of the facility for establishing external calls.

Calls to internal directory numbers or CN-numbers via the public network or private network have the possibility to be translated into DDI numbers by the individual number translation table.

For further information please refer to the document Individual Number Translation on page 1 (170/155 34-ASB 150 02 Uen).

This gives low-cost tele-offices which use fictive numbers in combination with ACD-groups, PBX Groups, Operator, mailboxes, Automated Attendants and fax servers the advantage to identify the reason of a call even without having ISND CLIP information available.

Example of use (general):

For the common call pick-up function the calls are directed to and queued at the fictive number.

Members of the group have assigned the supervision function for the fictive number and can pick up calls from it.

It is possible to set direct diversion onto a fictive number – see also Diversion Direct (165/155 34-ASB 150 02 Uen).

This is especially useful, when it is required to handover the name assignment of the fictive number to the diversion address

Example (ACD):

A call centre which is operating for several different clients (or products) can announce a separate directory number (public number + fictive number) for each client/product. This will help the call centre agent to identify the reason of the incoming call easily. The agent then can adapt the welcome message to the reason of the call (e.g. agent can welcome the caller with the specific company/client information).

Example (Operator):

In business centres, where lots of different companies are located one operator can handle all the incoming traffic for all different companies at the same time. If each company has been assigned its own fictive number the operator can always identify to which company the call is aimed. Therefore the operator can welcome the caller with the specific company name.

## Operation

Calls to a Fictive Number are connected to an extension that is physically not available. To prevent the call from getting lost, direct diversion for a Fictive Number can be programmed via BMS or via the Operator instrument. Calls to Fictive Numbers can also be routed and/or deflected via a CT application (e.g. Call Centre Assistant).

### Names for Fictive Numbers

It is possible to enter the name for the Fictive Number and to choose if the name will be visible in the internal directory book. If a name is entered in the directory, but shall not be visible - this means that the name of the Fictive Number is shown on the display during traffic, but that it is not visible when scrolling through the internal directory book. This can be useful, when the internal directory book scroll list shall not be filled with hundreds of names e.g. for Fax-server solutions.

### Direct Diversion for Fictive Numbers

A Fictive Number can direct diverted (without delay) to a diversion destination.The diversion address is programmable via BMS and by Operator. Setting of the diversion address means activation of the diversion.

All internal directory numbers and CN-numbers can be programmed as a diversion destination.

The Operator can use the “Follow Me” sequence to set or change a direct diversion for a Fictive Number:

Activation of a direct diversion for a Fictive Number:

*21* <fictive number> * diversion address> #

Deactivation of a direct diversion for a Fictive Number:

#21* <fictive number> #

### CTI support for Fictive Numbers

The CTI support for Fictive Numbers includes the starting of a CTI monitor on a Fictive number, event reporting and routing as well as deflection of incoming calls.

For a more detailed description please refer to the facility description “COMPUTER TELEPHONY INTEGRATION (CTI)”, document
152/155 34-ASB 150 02 Uen.

### Display of the called number (B-party)

This feature gives the user of Fictive Numbers the possibility to classify incoming calls according to the number the caller originally dialled, also called B-party or Called Number. In all traffic states the number/name of the A-party and B-party is displayed. This feature is mainly used for ACD environments where it should be possible to classify incoming calls according to the A- and B-party number.

For a more detailed description please refer to the facility description “ACD Group”, document
105/155 34-ASB 150 02 Uen.

## Capacity

The Fictive Number facility can be organized in up to 16 Fictive Number series. Similar to an abbreviated number series, a Fictive Number series can be represented by one directory number, where the last one, two or three digits are replaced by a wildcard character:

8000 |  | one Fictive Number |
800? |  | 10 Fictive Numbers from 8000-8009 |
80?? |  | 100 Fictive Numbers from 8000-8099 |
8??? |  | 1000 Fictive Numbers from 8000-8999 |

The amount of fictive numbers in all 16 series is restricted to a maximum of 1000 numbers. This means that there can be a maximum of either:

1 |  | N??? series |  | including 1000 Fictive numbers |
10 |  | NN?? series |  | including 1000 Fictive numbers |
16 |  | NNN? series |  | including 160 Fictive numbers |
16 |  | NNNN series |  | including 16 Fictive numbers |

Of course any combination of Fictive Number series of the type NN??, NNN? and NNNN is possible too, as long as the overall amount of Fictive Numbers does not exceed 1000 numbers.

It is possible to associate a Fictive Number series for each of the possible 16 tenant groups.

## Limitations

- It is not possible to make a call to a fictive number via a programmed supervision key.
- Name strings within the telephone directory cannot be provided for all fictive numbers, because of the limited storage capacity of the internal directory book – see also Telephone Directory (481/155 34-ASB 150 02 Uen).
- The function bypass of call diversion for fictive numbers is not available.
- The operator can only change the direct diversion address for a single Fictive Number but not for Fictive Number series.
- Following directory numbers will not be supported as diversion address:

- S-bus terminals, because they are dedicated as trunk individuals.
- Individual mailbox
- Common abbreviated numbers
- Route numbers
- Trunklines

- The internal directory book can only hold a maximum of 400 directory entries. Programming of names for fictive numbers is only possible, if there is enough space available for a new entry in the internal directory book. Therefore not all of the 1000 possible Fictive Numbers can have an associated name.

## Programming

5409 |  | Create a fictive directory number

5509 |  | Delete fictive number series

5612 |  | Alter fictive directory number series

5810 |  | Show fictive number series

2530 |  | Diversion address for fictive numbers

2830 |  | Fictive numbers open for tenant

6501 |  | Directory name

## Equipment

The following features for the fictive number facility are affected by the FECU:

- usage of more than 16 fictive numbers; without FECU the rest of the fictive numbers are handled as blocked directory numbers and any access to such a number shall result in a FECU warning
- direct diversion from fictive numbers; without FECU no diversion is executed and a FECU warning is generated
- CTI monitoring
