You must install Desktop Experience prior to installing Ivanti Voice; otherwise, the Ivanti Voice Server installation will be interrupted by a prompt to install Desktop Experience before continuing the Ivanti Voice installation.

SIP Hardware Requirements

Ensure all gateways and telephones are:


RFC-3261 SIP/2.0 UDP-compliant.

RFC-2833 telephony signals compliant (for DTMF recognition).

Ensure all SIP endpoints (including the voice server) can access the SIP Soft Switch for telephone number-to-IP address mapping.

Network Requirements and Recommendations

Required: Assign a static IP address to the Ivanti Voice server target host computer.

Required: The following network settings must be configured in the Advanced TCP/IP Settings dialog box on the DNS tab of the network interface: the DNS suffix should be specified; there must be at least one DNS server configured; this connection address, with the configured DNS suffix, must be registered with DNS. Verify the settings by clicking Start > Run to open the Windows command prompt, then type nslookup <name>, where <name> is the value of the Computer Name field. The command should successfully find the IP address.

Recommended: Use a 100Mbit LAN with switches. Do not use hubs.

Recommended: Install your gateways and other endpoints on the same IP network. Do not install IP gateways between endpoints. If you install gateways between endpoints, implement some type of Quality of Service (QoS) technology, such as Cisco CBWFQ/LLQ (Class-Based Weighted Fair Queuing/Low Latency Queuing), on the egress ports of all gateways through which voice traffic will travel.

License File Requirement

ISM provides a custom digital license file to each Ivanti Voice customer. License files contain information such as the modules licensed, customer name, customer ID, partner name, the name of the person who generated the license file, etc., and might contain expiration dates for licensed features.

Obtain a license and copy it to the Ivanti Voice server host computer. If you do not have a license file, Ivanti Voice runs only in a demonstration mode, allowing the following limited functionality:

4 IVR ports

2 Unified Messaging ports

2 Auto Attendant ports

2 agents

1 supervisor

5 phone entries

1 Statistic Console connection

Historical reporting

Quality Management

1 Quality Management supervisor

1 Quality Management concurrent recording channel

You can add a license file into your configuration later or replace an existing one, if necessary. Refer to the online help topic "Server Administration" for more information.

System Reliability and Availability

Since Ivanti Voice is a critical application to your business, consider redundancy and backup options to ensure Ivanti Voice reliability and availability. For information on these topics, contact your ISM representative.

Database Planning

If you are using a SQL Server database, refer to the online help topic "Ivanti Voice Database Details" for database-related planning issues.

In addition, you may want to integrate other databases with Ivanti Voice, as Ivanti Voice can access databases for caller authentication, customer information, and other purposes.

Integration Options

Ivanti Voice uses an open integration API to integrate with various database-driven applications, such as ticketing, service management, etc. The integrations enable automatic screen-pops displaying customer information based on information arriving with a call, such as customer ID, ticket number, etc.

Configuration with Ivanti Products

Ivanti Voice comes ready to configure with the following Ivanti products:

Ivanti Service Manager - If you plan to configure Ivanti Voice with the ISM application, you can install ISM either before or after installing Ivanti Voice. The configuration requires access and administrator rights to the ISM Administrator and Call Logging modules.

Foundation ITSM, CSM, and GMEE - Install the Foundation client before you install the Ivanti Voice server to avoid having to manually register the configuration component with Ivanti Voice.

GoldMine CE and PE - If you plan to configure Ivanti Voice with GoldMine, install GoldMine before installing Ivanti Voice. Installing GoldMine after Ivanti Voice results in irrevocable data loss.

Phone Options: Desktop Phone vs. Softphone

Each Ivanti Voice Communicator or Agent Dashboard can be used in lieu of a SIP-enabled desktop phone. The Communicator is essentially the softphone. The Agent Dashboard implements the softphone in addition to the agent-specific functionality. The agent may choose to use either the softphone (which is part of the Dashboard) or to use the desktop phone instead.

The question of whether or not to use an SIP handset or an SIP softphone depends on budget, management, and deployment requirements. Use the following comparison table to decide which type of phone is right for your environment.


SIP Softphone

SIP-enabled desktop phone


A software-based phone that functions like a typical desk phone. To use a softphone, the computer must have full duplex audio hardware (enabling simultaneous record/playback) and a headset/microphone. The computer software handles the codec processing. The softphone is often used in remote installations or used with teleworkers to limit the cost of deployment as well as to make it easier to manage remote phones from the IT staff.

A conventional physical phone but with built-in SIP technology. It uses an Ethernet port (instead of a normal phone jack) to communicate with the Contact Center server and other SIP hardware. Codecs are located within the phone hardware. You must configure the phone to work with your environment.


Usually less expensive when compared to a physical handset that has similar features. (The Agent Dashboard has a free built-in softphone, so no additional purchase is necessary.)

Can access the Ivanti Voice Global Address Book.

Constantly available, even when your computer is not running.


The softphone is not available when its host computer shuts down.

Purchased separately. Some models are relatively expensive.

Text-to-Speech (TTS) Integration Option

Text-to-Speech (TTS) engines are applications that read text aloud. Contact your sales representative to learn about Microsoft SAPI v5 support.

When installing a TTS engine, install it so all users can access it, not just you.

You can install multiple TTS engines both before and after installing Ivanti Voice. Ivanti Voice requires a TTS engine for each language for which you plan to use dynamic prompts. If you do not have a TTS engine for a language IPCM uses, you can alternatively record prompts for that language, but doing so prevents you from using variables. For information on prompts and variables, refer to Preparing for Incoming Calls. For information on basic TTS configuration, refer to the online help topic "Voice Server Configuration."

Backup Server Option

Ivanti recommends setting up a backup server to run Ivanti Voice if the primary host computer goes down.

To Set Up the Backup Server:

1.Replicate your Ivanti Voice server installation on the backup server.

The backup server must have its own license.

2.Open the HostConfiguration.xml file and Addressbook.xml file in the <install_dir>\Data directory on the backup server, and verify all instances of the Host Name element are set to the name of the backup server (search for Host Name in the HostConfiguration.xml file to locate all instances of the element). Remember to save the file if you make changes.

After your Ivanti Voice deployment goes live, keep the backup server up to date. To do this, regularly overwrite the following directories and files on the backup server with the versions on the primary server:

The <install_dir> is usually C:\Program Files\Ivanti\IP Communications Management.






Each time you copy the HostConfiguration.xml file to the backup server, change all instances of the Host Name element in the version of the HostConfiguration.xml file on the backup server to the name of the backup server.

To manually change your Ivanti Voice environment to use the backup server when the primary server fails:

  1. Reconfigure the gateway to direct calls to the backup server instead of the primary server.
  2. Reconfigure each Agent Dashboard to connect to the backup server:

Restart each Agent Dashboard. The Connect to Contact Center dialog box open upon restart.

In the Connect To section on the Connect to Contact Center dialog box, do one of the following:

Select the Discovered Server radio button, then select the name of the backup server in the Server Name drop-down list.

Select the Network Address radio button, then enter the name and port of the backup server the Host Name and Port fields.

Ivanti Voice Deployment Process

To deploy Ivanti Voice:

1.Use the information in this chapter to plan your setup and prepare your environment.

2.Set up a database for storing Ivanti Voice data.

3.Run the Ivanti Voice installation wizards. Refer to Installation.

4.Create the Dial Plan. Refer to Dial Plan.

5.Determine if the delivered user roles meet the needs of your business. If not, configure the roles as needed. Refer to Security Plan.

6.Create user profiles for all Ivanti Voice users. Refer to Organizing the Contact Center.

7.If you purchased Contact Center licenses, configure the following: create skills and skill groups, create agent groups and add agents to groups, configure individual agent skills and settings, create and configure routing rules, create services, create queues or modify default queues to meet your business needs. Refer to Organizing the Contact Center.

8.If your business requires one or more custom voice applications, use Application Builder to create them. Refer to Preparing for Incoming Calls. Ivanti Voice ships with three UM applications that suit the basic voice application needs of most non-contact center businesses. Refer to Office Phone System for information regarding how these applications operate.

9.If you create a new voice application, use Applications Selector to register the voice application with Ivanti Voice and configure how Ivanti Voice uses it (start criteria). Refer to Preparing for Incoming Calls.

10.Use the Management Portal to configure the Unified Messaging (UM) system-wide and user settings. Refer to Office Phone System.

11.Configure each installation of the Communicator softphone and all SIP-enabled desktop phones in your environment. Refer to Ivanti Voice Communicator for information. For desktop phone configuration, refer to the instruction manual included with the phone


Make individual changes to your deployment at any time, according to your business and network needs, without repeating the entire deployment process. Changes typically include adding extensions, users, and agents as your business expands, modifying voice applications in Application Builder, changing network settings to accommodate greater bandwidth, updating user profile information, etc.
