Notes
Three Party Conference via the Telephone System.
An incoming – or doorphone call will be signalled to the conference with the call waiting tone
if the called extension is part of the conference.
The Pick Up of a call is only possible by the extension who established the conference
(Conference Manager) by pressing the SPLIT button and selecting the call with the next
button. The other members of the conference are put on hold until the conference manager
has finished the enquiry call by pressing the ESC button after which he can re-establish the
conference with the SPLIT and the CONFERENCE button. If an extension replaces the
receiver then that extension is disconnected from the conference and can only be re invited
via the conference manager. The conference is cancelled as soon as the conference
manager replaces his receiver.

Call charges are incurred for every participant of the conference. If you hear an error tone
instead of an exchange dial tone, then the holding of a call in the exchange is not possible.
Press the ESC button to return to the original call. The Three Party Conference is not
possible if you hear the error tone after pressing the CONFERENCE button. Press the ESC
button to reconnect to the original call. Press the CONFERENCE button if you wish to clear
an established ISDN Three Party Conference. You are connected to the party that you last
invited into the conference .The first called party is put on hold.
