Operations during a Call

Next, you may repeat the entire enquiry and conference call procedure

to include another participant in the conference call. A conference

call can include up to 4 participants.

To do so:

First press the line key corresponding to the current conference
call (“Lx” is specified on the screen).

The conference call is placed on hold.

NO TO CALL

Then dial the number for the new internal or external party to
be contacted.

All of the usual services for dialling internal or external numbers are

available.

CONFERENC

Once again, press the dynamic function key shown on the
left, once this new party has answered your call.

The conference call now includes 4 participants.
Or, you may simply withdraw from the conference call:

Replace the handset or press the “C” key in handsfree mode.

This has the same result as a transferring a call between your two

parties, as your extension is now free.
On the other hand, if one of your parties withdraws from the con-

ference call, that will result in the call now being a single call with

the remaining party.

Notes:

If there are more than 2 parties on your telephone, the con-

ference call will be established between the party currently

conversing with you, and the last party who was placed on

hold.

Your extension may also be subject to enquiry calls, refer

back calls, transfers and conference calls initiated by third

party sets.
