Outcalling allows the DEFINITY AUDIX system to call subscribers
and inform them of new messages.
If an outcall is placed to a rotary
phone or pager, you will not be
able to retrieve your messages.
For this reason, assign Outcalling
only to touch-tone phones unless
you are using this feature for message

Outcalls are not placed while you
are logged on to the system. If you
hang up without reviewing your
new messages, outcalls will be
placed using the current schedule.
The maximum number of digits
subscribers can specify as their
outcall number may be limited to
prevent subscribers from requesting
long-distance calls (the maximum
length is 60 digits). Limiting
the number of digits may prevent

This feature is often used on systems that do not have message-waiting lamp
capability. It may also be useful for subscribers who work at home or another
location, or who wish to be notified promptly of new messages during or after
regular working hours. Further, this feature can be used to notify subscribers of
new messages by calling their pagers or radio pagers.
Outcalling permission should be given with care, because it uses ports and trunk
lines that might otherwise be used for standard voice mail and call answer
operation. If outcalling is used excessively, or if the system is undersized, it may
tax system resources. Because even routine messages trigger outcalls,
outcalling can use resources unnecessarily. A good way to make judicious use of
outcalling is to use the Priority Outcalling feature in conjunction with the Priority
INTUITY Message Manager (IMM) uses the Outcalling feature to complete a call to
a subscriber’s telephone; this can cause port contention with other Outcalling
calls. The number of Outcalling ports may need to be increased when using
The DEFINITY AUDIX system, like all voice messaging and automated attendant
systems, is subject to unauthorized long distance call attempts (toll fraud). But
the system administrator can take steps to minimize the risk.
To minimize the possibility of toll fraud, administrators should turn off
outcalling on a per-subscriber basis via the Subscriber or Class of Service
screens. The number of digits used for outcalling can also be restricted on
a system-wide basis using the System-Parameters Outcalling screen.
The system administrator activates the Outcalling feature using the
System-Parameters Outcalling screen. The fields on this screen allow the
administrator to set certain restrictions on outcalling activity. After outcalling has
been activated and administered on the screen, an audit must be run; otherwise,
the Outcalling feature will not work. Note that any time the administrator changes
the number of ports available for the Outcalling feature, the switch-translations
audit must be run to activate those changes.
Systems with Outcalling enabled may require additional voice ports depending
on the number of people who use the feature, the length of outcalls, and the
frequency of notification attempts. For example, a successful (answered) outcall
may take 20 seconds to hang up, while an unsuccessful outcall may take up to
one minute for the system to hang up (the system waits for potential input before
timing-out and ending the call).
