## Camp On – Inquiry

## Definition

An extension who, on inquiry, encounters busy tone, can camp the latest individually parked party on to the busy extension, via a transfer request.

## Use

Allows an OPERATOR equipped with an DBC 223, DBC 213 or DBC 662 telephone or other extension to extend calls even if the called party is busy. This enables the extending party to go free and answer new calls.

## Operation

### DBC 211, DBC 601, DBC 220, DBC 222, DBC 212, DBC 631, DBC 223, DBC 213 and DBC 662 telephones

An extension connected to an external party initiates inquiry to an internal party.

If the inquirer receives busy tone, the external call can be camped on to the busy extension as follows:

1. Press Transfer.

- Lamps for both parked and called parties extinguish. The display shows idle information provided no other calls are parked.

The camped on party receives music on hold or silence.

See also facility description Call Waiting Indication (145/155 34-ASB 150 02 Uen).

The party who receives the camp on hears a short ring burst (analogue telephone two short tone bursts in handset).

If camp on is forbidden, depression of the Transfer‑key will be ignored.

### DBC 210, DBC 199 and non system instruments

An extension connected to an internal party initiates inquiry to another internal party.

If the caller receives busy tone, the external call can be camped on to the busy extension as follows:

1. By replacing handset, whereupon caller's telephone is free.

- Camped on party receives music on hold or silence.

See also facility description Call Waiting Indication (145/155 34-ASB 150 02 Uen).

If camp on is forbidden, the external party will recall the transferring extension.

### Recall

If a camped on external call remains unanswered after a programmable time, the transferring party will be recalled.

Note

Camped on internal calls do not lead to recall.
