## Inquiry

## Definition

Inquiry means, during an ongoing call, the possibility to initiate a new call. The ongoing call will be parked automatically.

## Use

Inquiry is used when, for example, one wishes to obtain information from a third party during an ongoing call.

When the inquiry call ends, the inquirer can disconnect this call and revert to her/his original call partner.

The third party (inquiree) can remain parked when the caller returns to the original party, thereby allowing the caller to switch between the two calls.

See also Refer Back (441/155 34-ASB 150 02 Uen).

When an inquiry call has been established the original call partner can be transferred to the inquiree.

See also Transfer (485/155 34-ASB 150 02 Uen).

If the inquiree is busy, the parked call can be camped on to the inquiree.

See also Camp On (146 - 148/155 34-ASB 150 02 Uen).

Inquiry is also possible to extensions in a superior system or subscribers in the public network.

See also Subsystem (462/155 34-ASB 150 02 Uen).

## Operation

### Digital Telephones

#### Initiation of inquiry

An inquiry is initiated as follows:

1. Press free traffic function key (Line 1, Line 2 *, Inquiry, External line key etc.)

- Ongoing call is automatically parked individually. Associated lamp for parked call's traffic function key starts to flash slowly.
- If system telephone has a display, this goes blank. From these telephones the inquiry call is to be regarded as a new call.
- The lamp for the occupied traffic function flashes to confirm connection and dial tone is heard. The extension user can now dial the desired directory number.

#### Reversion

Reversion to the parked party is achieved as follows:

1. Press traffic function key for parked party.

- Lamp flashes to confirm connection.
- If inquiree remains parked lamp will flash slowly.
- If inquiree replaces handset lamp will extinguish.

#### Inquiry via name selection key

1. Press name selection key.

- Ongoing call will be parked automatically at same time as one of the free traffic functions, i.e. Line 1, Line 2 (not available on the BASIC Telephone) or Inquiry will be seized automatically.
- Number stored on name selection key will now be transmitted on seized traffic function.

### Analogue Telephones

#### Initiation of inquiry

Inquiry is initiated as follows:

1. Press R (Recall)-button.

- (Digit “1” is dialled on analogue rotary dial telephones without R-button)
- On initiation ongoing call is parked and new dial tone is obtained.

1. Inquirer then dials relevant directory number.

#### Reversion

Reversion to the parked party is achieved as follows:

1. Press R-button (digit “1” for rotary dial telephones).

- If it is desired to disconnect the inquiree, the inquirer presses the R-button and 1, and to retain the inquiree R-button and 2.

If only the R-button is pressed, reconnection of the parked party will take place automatically after three seconds.

In the event of uncompleted inquiry from an analogue rotary dial telephone, the user must replace the handset and the extension will be rerung by the parked party.

## Capacity

The number of simultaneously ongoing inquiry calls is limited only by the number of traffic functions on the system telephones.

On an ANALOGUE Telephone only one inquiry call at a time can be handled.

## Limitations

Inquiry can only be initiated during an ongoing answered call.

If a new traffic function key is pressed before answer, the original call will be disconnected.

For initiation of inquiry calls the same prerequisites apply as for normal incoming internal or external calls.
