automatic answering (auto-
answer) on the IP phone for
incoming intercom calls. If auto-
answer is enabled on the IP phone,

intercom call. If auto-answer is
disabled, the phone rejects the
incoming intercom call and sends a
busy signal to the caller. By
default, the microphone is OFF and
auto-answer is ON.

configure outgoing Intercom
calls using the Icom button. Con-
tact your system administrator
for more information.
