Cisco CUCM 91 ISO: What It Is and How to Install It
Introduction
If you are looking for a reliable, secure, scalable, and manageable solution for your enterprise communication and collaboration needs, you might want to consider Cisco Unified Communications Manager (CUCM). CUCM is an enterprise call and session management infrastructure that streamlines team communication and collaboration for todays hybrid workforce. It unites registered IP phones, mobile devices, desktop computers, and other endpoints into a single network that supports voice and video calling, messaging, presence, and mobility.

But how do you install CUCM on your servers? One way is to use an ISO image. An ISO image is a file that contains all the data of an optical disc, such as a CD or DVD. By using an ISO image, you can avoid the hassle of physical media and save time and bandwidth. You can download the ISO image from Ciscos website or copy it from a running CUCM server. You can then mount the ISO image on your virtual machine (VM) or burn it on a disc.
One of the latest versions of CUCM is 9.1. This version introduces new features such as jump upgrade, which allows you to upgrade from older versions directly to 9.1 without intermediate steps. It also streamlines the license migration process using Enterprise License Manager. Moreover, it offers improved performance, security, compatibility, and user experience.
In this article, we will explain what Cisco CUCM 91 ISO is and how to install it on your servers. We will also cover the topology options, features, and capabilities of CUCM 9.1. By the end of this article, you will have a better understanding of how CUCM 9.1 can benefit your organization.
Installation Methods
There are different methods There are different methods to install CUCM 9.1 on your servers, depending on your needs and preferences. Here are the main ones:
Basic Install of Cluster
This method involves installing the publisher node first, then adding and installing subscriber nodes one by one. A publisher node is the primary node in a cluster that hosts the database and provides administration functions. A subscriber node is a secondary node that replicates the database from the publisher and provides call processing functions. You can use this method if you want to have more control over the installation process and customize each node individually.
To perform a basic install of cluster, you need to follow these steps:
Download the CUCM 9.1 ISO image from Ciscos website or copy it from a running CUCM server.
Mount the ISO image on the VM or burn it on a disc.
Boot the VM or server from the ISO image.
Select the basic installation option and follow the prompts to install the publisher node.
Repeat steps 2 to 4 for each subscriber node, making sure to select the subscriber installation option and provide the publisher nodes IP address and security password.
If you want to apply a patch during an upgrade, you can select the patch installation option and provide the patch file name and location.
After installing all nodes, you can configure pre-installed software such as Cisco Unified Serviceability, Cisco Unified Reporting, Cisco Unified OS Administration, and Cisco Unified Communications Manager Administration.
Touchless Install of Cluster
This method allows you to complete a full cluster installation in one seamless process. You can use this method if you want to save time and effort and automate the installation process. You need to provide server details for all cluster nodes in advance using an answer file. An answer file is a text file that contains configuration parameters for each node, such as hostname, IP address, timezone, username, password, etc.
To perform a touchless install of cluster, you need to follow these steps:
Create an answer file for each node using a template provided by Cisco or your own format.
Download the CUCM 9.1 ISO image from Ciscos website or copy it from a running CUCM server.
Mount the ISO image on the VM or burn it on a disc.
Boot the VM or server from the ISO image.
Select the touchless installation option and provide the answer file name and location.
Start the installation and monitor the progress on the console or through a web interface.
The installation will automatically install all nodes in the cluster according to the answer file parameters.
Add a Node to a Cluster
This method allows you to add and install a new node in an existing cluster. You can use this method if you want to expand your cluster capacity or replace a faulty node. You need to have access to the ESXi datastore where the CUCM VMs are stored and run recovery software on the new node.
To add a node to a cluster, you need to follow these steps:
Download the CUCM 9.1 ISO image from Ciscos website or copy it from a running CUCM server.
Create a new VM on the ESXi host with the same specifications as the existing nodes.
Power off the VM and edit its settings to enable booting from CD/DVD drive.
Upload the ISO image to the ESXi datastore where the CUCM VMs are stored.
Mount the ISO image on the VMs CD/DVD drive.
Power on the VM and boot from the ISO image.
Select the recovery software option and follow the prompts to install the new node.
Topology Options
Before you install CUCM 9.1 on your servers, you need to decide on the topology of your network. The topology refers to the physical and logical arrangement of your servers and devices. The main topology options for CUCM 9.1 are clusters, publisher nodes, and subscriber nodes.
Clusters
A cluster is a group of servers that work together to provide unified communications services. A cluster can have up to 20 nodes, depending on the server model and the number of devices and users. A cluster provides scalability and redundancy for your network. Scalability means that you can add more nodes to increase the capacity and performance of your network. Redundancy means that you can have backup nodes that take over the functions of a failed node.
A cluster consists of two types of nodes: publisher nodes and subscriber nodes. Each node has a unique hostname and IP address. The nodes communicate with each other using various protocols, such as TCP/IP, SIP, SCCP, H.323, MGCP, etc. The nodes also share a common database that stores the configuration and call data of the cluster.
Publisher Nodes and Subscriber Nodes
A publisher node is the primary node in a cluster that hosts the database and provides administration functions. There can be only one publisher node in a cluster. The publisher node allows you to configure, manage, and monitor the cluster using web-based interfaces or command-line tools. The publisher node also replicates the database to the subscriber nodes.
A subscriber node is a secondary node in a cluster that replicates the database from the publisher node and provides call processing functions. There can be up to 19 subscriber nodes in a cluster, depending on the server model and the number of devices and users. The subscriber nodes handle the incoming and outgoing calls from the endpoints and route them to the appropriate destinations. The subscriber nodes also provide backup functions for each other in case of a failure.
To configure database replication and synchronization between the publisher node and the subscriber nodes, you need to use Cisco Unified Database Replication Service (DRS). DRS allows you to create replication groups, assign roles, monitor status, troubleshoot issues, and perform backup and restore operations. Features and Capabilities
