Operations during a Call

When a call is established, your extension offers you the option of 

alternating between the handset only and handsfree modes, and 

between group listening and mute modes.
You may also control the listening volume for your extension’s 

handset or loudspeaker.
You also have access to various services for processing your calls, 

including:
•

Enquiry call to consult another internal or external party.

•

Refer back call between two on-line parties or broker’s call.

•

Call transfer between two parties.

•

Conference call with three or four participants.

You may also temporarily place a call on hold, in order to carry out 

a non-telephone related task, or you may park a call in order to pick 

it up on a different extension.

Loudspeaker Mode

When you participate in an incoming or outgoing conversation 

using the handset, you can, at any time, decide to activate your 

extension’s loudspeaker mode, so that a group of people may 

listen in on the ongoing conversation. To do so:

Â

The associated LED will light. Only your extension’s loudspeaker 

is activated, while the conversation continues on the handset (the 

extension’s microphone is inactive).
