## 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 an EXECUTIVE 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 ECONOMY-, STANDARD- or EXECUTIVE telephones is only possible when the telephone is busy, that is 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
