## Camp On – Incoming External Traffic

## Definition

Incoming external traffic to a busy individual answering position will be camped on to the answering position automatically.

## Use

The function is used for common answer and to queue calls when a normal extension is used as answering position for incoming external traffic.

The calling trunks are camped on to the answering position and are presented in the order of arrival.

### Function

An incoming call to a busy extension that is open for camp on will be camped on automatically.

The caller will hear ring control tone from the public exchange until the call is answered or he tires of waiting and goes on hook.

The called extension hears, if no other type of ringing is supplied, the call waiting indication as a short muted tone burst as indication that further calls are waiting.

An analogue telephone receives two tone bursts as camp on indication.

If the answer position is blocked for camp on subsequent calls will be presented only on programmed external line keys.

If the identified answering position does not answer the call within a certain time, the call will be diverted to the alternative answering position.

## Capacity

The number of camp-ons to an individual directory number is unlimited.

The calls are queued in the order of arrival.

## Limitations

Camp on is not possible if:

- The busy extension has a category that prevents camp on
- The traffic group matrix forbids interconnection of the parties
- The trunk is programmed for diversion to an alternative answering position when the normal answering position is busy

## Programming
