## Camp On – Internal Calls

## Definition

The possibility, to make a busy internal extension aware that a call is waiting.

## Use

An extension that calls a busy internal party can, without effecting intrusion, make the busy party aware that a call is waiting.

## Operation

### All telephones

#### To order camp on

1. Initiate normal call to another internal party.

- Busy tone is received.

1. Dial postdialling digit (normally 4).

- Called party receives short muted ring burst.
- Caller encounters silence.
- Analogue telephones receive call waiting tone in the handset.

1. For extensions equipped with a DBC 223, DBC 213 or DBC 662 telephone the menu key camp‑on may be pressed to activate the camp-on function.

The display shows “WAIT or W” as an indication that the call is camped-on to the busy extension.

#### Called party answer

If the caller chooses to accept the call, he terminates the ongoing call whereupon he/she is rung by the camped on call provided that Line 1 or Line 2 is free.

The called party receives ring signal.

The camped on party now receives ring control tone and the call is now to be regarded as a normal internal call to a free extension.

## Capacity

All extensions have access to this facility.

## Limitations

Several internal calls can be camped on to an individual extension.

Camp on to DBC 211, DBC 601, DBC 220, DBC 222, DBC 212, DBC 631, DBC 223, DBC 213 or DBC 662 telephones is only possible when the telephone is busy on both lines, otherwise the call is presented on Line 2.

## Programming

This command is only accessable via BMS:

2401 |  | Digit for camp-on

### Altering the postdialling digit

If a postdialling digit other than “4” is to be used this must be redefined.

## Equipment

None
