User Configuration Settings


This chapter contains settings that you configure when you add and update users. After you become familiar with the Cisco Voice Provisioning Tool, consider printing this chapter to use as a reference.

This chapter contains information on the following topics:

Considerations for User Settings

User Parameters (Basic User Settings) (for User Template and User Pages)

CallManager User Information Settings (for User Template and User Pages)

Cisco Unity User Information Settings (for User Template and User Pages)

User Settings for Bulk Provisioning

Considerations for User Settings

Consider the following information before you review the user configuration settings:

Most settings in the tables are considered optional; that is, you do not need to configure them to add or update a user (or user template).

For required settings, such as the CCM User Password, Confirm Password, CCM PIN, and Confirm PIN fields, an asterisk (*) displays next to the setting in the GUI.

For templates, you can leave most field(s) blank; enter partial data (for example, the area code only for the phone number); or specify the exact information as you want it to display for individual users.

Because some settings do not display in the GUI when you add a user or update a user, the order in the tables may not reflect the order of the settings in the GUI. This document does not distinguish the settings for additions or modifications; if the setting does not display on the page, you cannot configure it.

User Parameters (Basic User Settings)

Cisco Unity User Information Settings

Most settings in Table 11-3 are optional. For required settings, an asterisk (*) displays next to the setting in the GUI. You can leave the field(s) blank; enter partial data (for example, the area code only for the phone number); or specify the exact information as you want it to display for individual users.

The Cisco Voice Provisioning Tool does not support importing of existing Microsoft Exchange users. When you use a Cisco Unity server to add a user, the Cisco Unity server creates the Unity PIN and password and allocates it to the user. The Cisco Voice Provisioning Tool does not allow you to specify a Cisco Unity password when you add or modify a user record, although you may set the Unity PIN.

Use Table 11-3 in conjunction with the following sections:

Template Pages

Adding a User Template, page 6-2

Updating a User Template, page 6-3

User Pages

Adding a User, page 3-2

Updating a Single User, page 3-3

Updating Multiple Users at the Same Time, page 3-4

Table 11-3 Unity Settings for Users 

Setting
Description

PIN

Enter a password by using digits 0 through 9. To help protect Cisco Unity from unauthorized access and toll fraud, enter a long—eight or more digits—and non-trivial password.

To have Cisco Unity prompt the subscriber to set a new password, also check the User Must Change Password at Next Login check box.

The information that you enter in this field displays as encrypted text.

When you update a user record, click the Reset button to change the PIN.

PIN

Enter the new password again to confirm the entry.

The information that you enter in this field displays as encrypted text.

Message Extension

From the drop-down list box, choose the number that callers dial to reach the subscriber. Message Extension options include extensions for all phones associated with the user plus the Custom Extension options. If you choose a different product system after configuring this setting, this setting reverts to the default.

Custom Extension

If you want to use a different extension for voice mail than the extension that is designated for the phone, enter the value in this field.

Disabled by default, this field appears enabled when you choose Custom Extension for the Extension setting.

If you did not choose a Cisco CallManager product system or did not associate a phone or profile with the user, you must configure the Custom Extension setting.

Because the Cisco Voice Provisioning Tool does not validate whether the extension is used by another Cisco Unity user, verify that the extension is not used by another user in Cisco Unity before you enter the information in this field.

Display name

Cisco Unity creates a default display name for the subscriber, which you can modify. This is the name as displayed in the Cisco Unity Administrator, Exchange, Windows, and subscriber reports. In most cases, only the first 40 characters are displayed.

Fax ID

Enter the number that callers dial to send a fax to the subscriber. This number may be the same as the subscriber extension.

The Cisco Voice Provisioning Tool does not validate whether the value exists.

Subscriber Type

Choose the subscriber type that applies to the user.

Exchange—Regular subscribers have an Exchange mailbox and a Windows domain account. Cisco Unity creates the mailbox and Windows domain account at the same time that it creates the subscriber. Exchange 5.5 mailboxes are created in the Recipients container in the site; Exchange 2000 and Exchange 2003 mailboxes are created in the domain and organizational unit (OU) that you specified in the Cisco Unity Server Configuration Wizard during Setup. The user object for the subscriber in Active Directory or the Exchange 5.5 directory contains Cisco Unity-specific attributes. If you choose this type, you must enter a value either in the Extension or Custom Extension fields.

Internet—Internet subscribers do not have mailboxes on the local Exchange network. When Cisco Unity creates the Internet subscriber account, it creates an Active Directory contact (or Exchange 5.5 custom recipient) with Cisco Unity-specific attributes. The Extension field becomes optional when you check this check box.

Subscriber Template

From the drop-down list box, choose a subscriber template that is supported on the Cisco Unity product system that you chose for the user configuration.

SMTP Address

Disabled by default, this field appears enabled when you choose Internet Subscriber for the Subscriber Type.

Enter up to 128 characters for the e-mail (SMTP) address that is assigned to the Internet subscriber. If the remote message recipient that the Internet subscriber corresponds to uses Cisco Unity, enter the remote address in the following format:

VOICE:<Delivery Location Dial ID>_<Remote Primary Extension>
(for example, VOICE:123_5678)

If the remote message recipient does not use Cisco Unity, specify the e-mail (SMTP) address to which messages to the Internet subscriber will be sent:

SMTP:alias@domain.com
(for example, aabade@cisco.com)

Exchange Server

Choose the Exchange server (also referred to as the home server) where the subscriber messages are stored.

MailStore ID

Choose the mailbox store where subscriber messages are stored.

Class of Service

A class of service (COS) defines limits and permissions for using Cisco Unity. For example, a COS:

Controls access to the Cisco Unity Administrator and to features, such as Text to Speech e-mail or live reply.

Controls how subscribers interact with Cisco Unity. For example, a COS dictates the maximum length of subscriber messages and greetings, whether subscribers can choose to be listed in directory assistance, and whether subscribers can send messages to a public distribution list.

Specifies the restriction table used to control the phone numbers subscribers can use for fax delivery, message notification, call transfer, and other tasks.

A COS is specified in each subscriber template; thus, a subscriber is assigned to the COS that is specified in the template upon which the subscriber account is based.

The Cisco Voice Provisioning Tool does not validate this setting.

User Must Change Password at Next Login

Check this check box when you have set a temporary phone password, and want the subscriber to set a new password the next time that the subscriber logs on to Cisco Unity by phone.

Encourage subscribers to specify long—eight or more digits—and non-trivial passwords as a way to help protect their accounts from unauthorized access and toll fraud.

User Cannot Change Password

Check this check box to prevent the subscriber from changing the phone password. Use of this setting is most applicable for accounts that can be accessed by more than one person. When you check this check box, also check the Password Never Expires check box.

If you leave this check box unchecked, subscribers can use the Cisco Unity phone conversation or the Cisco Unity Assistant to set their phone passwords. Encourage them to specify long—eight or more digits—and non-trivial passwords as a way to help protect their accounts from unauthorized access and toll fraud.

The Cisco Voice Provisioning Tool does not validate this setting.

Password Never Expires

Check this check box for low-security subscribers or for accounts that can be accessed by more than one person.

The Cisco Voice Provisioning Tool does not validate this setting.
