Attendant-Based Services
MD Evolution – Dialog 4425 IP Vision 180
Other Attendant-Based Services
As indicated, your facility’s attendants may establish you as the
target for any of the following services:
•
Call offer or intrusion service: When you are in the middle of an
ongoing call, this service enables them to interrupt your call to
present an urgent call for you.
• Do not disturb override service: When your extension has a
do not disturb status, (see also the “ Call Forwarding Services ”
section), this service also enables the attendants to override the
do not disturb status in order to present an urgent call for you.
In the first case, when the attendant activates a call intrusion, you may
find yourself in a 3-way conference call with your first caller and the
attendant. Usually, a warning tone is heard at a regular frequency
during this conference call to remind the parties that they are still
under a call intrusion status.
The attendant may then speak to you, but not privately.

Alternatively, you may press the flashing line key on which the
attendant’s call is presented. Your first caller is then automatically
placed on hold, and you may then speak privately with the attendant.
In the second service, when the do not disturb status is overridden
by the attendant, his/her call is presented just as a normal call would
be, and which you may answer normally.
These same services may also be performed from properly author-
ised non-IP third party sets.
However, you do not have access to these services from your
Dialog 4425 IP Vision extension, in relation to third party sets.
Notes:
Certain extensions (such as yours) may possibly be equipped
with a permanent protection against call intrusion.
Depending on the configuration for your facility defined by
your system administrator, these services may be used
from specific extensions that are duly authorised, without
any warning tones being emitted. This refers to the silent
call monitoring service.
