Operations for Incoming Calls

Â

Press the Loudspeaker key on your extension.

You are now directly connected to the party calling the other

extension.

Notes:

The prefix “13” is the one usually used to access the call

pick-up service. It may, however, have been modified by

your system administrator.

Rather than dialling the number of the extension to pick-up,

you may also press the repertory key where this number

may have been saved.

Your extension may also be subject to call pick-ups from

third party sets.

Certain extensions (such as yours) may possibly be equipped

with permanent protection against call pick-up. If this is the

case, this service will obviously be refused on these exten-

sions (and vice-versa).

É

Press this key to activate silent ringing for incoming calls.
