Unified Communications
Subscribers
Now that you have completed the general setup of the Cisco Unity system, it is time to
begin adding subscribers. A number of options are available not only to the administrator
but also to each subscriber who is added into the Cisco Unity system. This chapter discusses
the features and options that are available to both the administrator and the subscriber.
The subscriber experience with Cisco Unity will be based largely on the manner in which
the system is configured by the administrator at this point. Much of the work that has been
accomplished in getting to this phase of the installation lays the groundwork to support
subscribers. Software add-ons, call routing, system schedules, and all the other aspects of
the system come down to this. The system should be subscriber- and caller-friendly. These
two facets of the overall experience can have a profound effect on the usability of the
system and, of course, on those who must use the system.
Understanding Cisco Unity Global Subscriber
Accounts, Templates, and Settings
Global subscriber settings influence many aspects of Cisco Unity system behavior for
individual subscribers. Changes made in these areas affect many, if not all, subscribers.
There are a number of changes that can be made to an individual subscriber’s account;
however, these changes affect only that one account. There are areas of subscriber settings
that affect a subset of subscribers or that may have a global effect on all Cisco Unity
subscribers. These settings include:
Account Policy
Class of Service (COS)
Public Distribution Lists
Subscriber Templates
Good planning and preparation can make your administrative task of adding subscribers
much easier. This section focuses on considerations you must keep in mind when planning
and preparing to add subscribers.
98 Chapter 4: Unified Communications Subscribers
To benefit fully from this section, it is recommended that you have the following prerequisite
skills and knowledge. (If you need a quick review of either topic, see Chapter 3, “Setting Up
Cisco Unified Communications,” where you can find more information.)
A working knowledge of the Cisco Unity System Administrator
A basic understanding of Cisco Unity setup and configuration
Setting Account Policy
The settings made on the Account Policy page determine telephone password restrictions and
how and when accounts become locked out. By default, the Number setting is set to six invalid
attempts within 30 minutes. A locked-out account is reinstated after 60 minutes. There is also
a setting to allow for “no account lockout.” Each of these settings influences the security of the
system and affects only telephone access to the subscriber’s Cisco Unity account for the Cisco
Unity system over the telephone. The settings have no effect on account policy for other
Microsoft Windows or Exchange servers. When a setting is changed on the Account Policy
page, it takes effect immediately.
Additionally, you can alter the minimum required length of a password. This setting takes effect
for all accounts except those that are permitted a blank password. The last setting, which
governs telephone password history, determines whether subscribers must generate a unique
password each time they change it. You can also simply set the number of unique passwords
that the subscribers need to generate.
It is highly recommended, as a security measure, to require subscribers to set passwords. These
passwords should also expire on a regular basis, thereby forcing subscribers to change their
passwords occasionally. The first setting, Maximum Password Age, is a setting that may not act
in a global fashion. If a system administrator changes the number of days until the passwords
expire, this will change for everyone on the system except those subscribers whose accounts are
set with a password that never expires. The change takes effect immediately and all subscribers
whose accounts do not match the setting are required to make the change at the next login over
the telephone. Be aware that compulsory periodic password changes can cause some
consternation among the subscriber population. Thus, you may need to temper the need for tight
security in consideration of the subscribers’ patience (or lack thereof).
Describing COS
COS is a subgrouping of users who share a collection of common system features and
privileges. This concept of COS is familiar to most telephony installers. Figure 4-1 shows the
COS page.
