<p>CUCM version 8.6.2 was released in July 2012 as a minor update to version 8.6.1. It introduced some new features and enhancements such as:</p>


<ul>


<li>Support for Cisco Jabber for Windows</li>


<li>Support for Cisco Unified IP Phone 6900 Series</li>


<li>Support for Cisco Unified Border Element (CUBE) on Cisco Integrated Services Routers Generation 2 (ISR G2)</li>


<li>Support for IPv6 on SIP trunks</li>


<li>Support for Secure LDAP (LDAPS)</li>


<li>Support for Smart Licensing</li>


</ul>


<p>To use CUCM 8.6.2, you need to purchase a valid license from Cisco or an authorized reseller. The license consists of two types of units: device license units (DLUs) and node licenses. DLUs are assigned to each device that is connected to CUCM, such as IP phones and applications. Node licenses are required for each server that runs CUCM. The number of DLUs and node licenses depends on the size and complexity of your network.</p>


<p>Some users may want to use a keygen to generate a license for CUCM 8.6.2 without paying for it. A keygen is a program that can create a license file based on some information such as the MAC address of the server or the number of devices. A keygen can bypass the license verification process and make CUCM think that it is activated legally.</p>


<p>However, using a keygen is not recommended for several reasons. First, it is illegal and unethical to use a software product without paying for it. You may face legal consequences if you are caught by Cisco or the authorities. Second, it is risky and unreliable to use a keygen. You may download a malicious program that can harm your system or steal your data. You may also get a license file that is invalid or expired, and that can cause your CUCM to malfunction or stop working. Third, it is unfair and disrespectful to the developers and engineers who work hard to create and maintain CUCM. They deserve to be compensated for their efforts and skills.</p>


<p>Therefore, we strongly advise you to purchase a valid license from Cisco or an authorized reseller if you want to use CUCM 8.6.2. It is the right thing to do, and it will ensure that you get the best performance, security, and support from CUCM.</p>


<p>If you still want to use a keygen, please proceed with caution and at your own risk. We are not responsible for any damages or losses that may result from using a keygen. In this article, we will show you how to install CUCM 8.6.2 on your own hardware, how to use a keygen to generate a license for it, and how to troubleshoot some common issues with it.</p>


<h2>How to install CUCM 8.6.2 on your own hardware</h2>


<p>CUCM 8.6.2 can be installed on your own hardware if you meet the minimum requirements for CPU, memory, disk space, and network connectivity. You can find the detailed specifications here. Alternatively, you can use a virtual machine (VM) that meets the same requirements.</p>


<p>To install CUCM 8.6.2 on your own hardware, you need to follow these steps:</p>


<ol>


<li>Download the ISO file from Cisco or a trusted source. The ISO file contains the installation image of CUCM 8.6.2 and can be obtained from Cisco's website if you have a valid account and contract. Otherwise, you may find it on some online forums or torrent sites, but be careful of the authenticity and integrity of the file.</li>


<li>Burn the ISO file to a DVD or create a bootable USB drive. You can use any software that can burn ISO files to DVDs or USB drives, such as ImgBurn or Rufus. Make sure that the DVD or USB drive has enough space to hold the ISO file.</li>


<li>Boot from the DVD or USB drive and follow the installation wizard. Insert the DVD or USB drive into the server or VM that you want to install CUCM 8.6.2 on, and restart it. You may need to change the boot order in the BIOS settings to boot from the DVD or USB drive first. Once you boot from the DVD or USB drive, you will see the installation wizard that will guide you through the installation process.</li>


<li>Configure the basic settings such as hostname, IP address, DNS, NTP, etc. During the installation wizard, you will be asked to enter some basic settings for your CUCM server, such as:</li>


<ul>


<li>The hostname of the server</li>


<li>The IP address, subnet mask, gateway, and DNS servers of the server</li>


<li>The NTP servers that will synchronize the time of the server</li>


<li>The security password that will protect the access to the server</li>


<li>The application username and password that will be used to log in to the CUCM administration web page</li>


<li>The SMTP server that will send email notifications from CUCM</li>


<li>The type of installation: Publisher or Subscriber</li>


<li>The cluster security mode: Mixed Mode or Non-Secure Mode</li>


</ul>


<p>Make sure that you enter these settings correctly and remember them for future reference.</p>


<li>Activate the services and features that you need. After configuring the basic settings, you will be asked to select which services and features you want to activate on your CUCM server, such as:</li>


<ul>


<li>Cisco CallManager: The core service that provides call processing and signaling functions</li>


<li>C isco TFTP: The service that provides file transfer functions for IP phones and applications</li>


<li>Cisco CTIManager: The service that provides computer telephony integration (CTI) functions for applications such as Cisco Attendant Console and Cisco Unified Contact Center Express</li>


<li>Cisco AXL Web Service: The service that provides administrative XML (AXL) functions for applications such as Cisco Unified Communications Manager Bulk Administration Tool (BAT) and Cisco Unified Communications Manager Assistant</li>


<li>Cisco Extension Mobility: The feature that allows users to log in to different IP phones and access their personal settings and preferences</li>


<li>Cisco Unified Mobility: The feature that allows users to use a single number reach (SNR) function to forward incoming calls to their mobile phones or other devices</li>


</ul>


<p>You can select the services and features that you need based on your network requirements and preferences. You can also activate or deactivate them later from the CUCM administration web page.</p>


<p>After selecting the services and features, the installation wizard will proceed to install CUCM 8.6.2 on your server. This may take some time depending on your hardware specifications and network speed. Once the installation is complete, you will see a confirmation message on the screen. You can then reboot your server and access the CUCM administration web page from a web browser using the application username and password that you set earlier.</p>


<h3>How to use a keygen to generate a license for CUCM 8.6.2</h3>


<p>As mentioned before, using a keygen to generate a license for CUCM 8.6.2 is not recommended, as it is illegal, risky, and unfair. However, if you still want to use a keygen, you need to follow these steps:</p>


<ol>


<li>Find a reliable keygen program that works for CUCM 8.6.2. There are many keygen programs available on the internet, but not all of them are trustworthy or compatible with CUCM 8.6.2. You need to do some research and find a keygen program that has positive reviews, feedback, and ratings from other users who have used it successfully for CUCM 8.6.2. You also need to scan the keygen program with an antivirus software before running it, as it may contain malware or viruses.</li>


<li>Run the keygen program and enter your MAC address or other information as required. Once you have downloaded and scanned the keygen program, you can run it on your computer or server where you have installed CUCM 8.6.2. The keygen program will ask you to enter some information such as the MAC address of your server, the number of DLUs or node licenses that you want, or the expiration date of the license. You need to enter these information correctly and click on the generate button.</li>


<li>Copy the generated license file to your CUCM server. The keygen program will create a license file with a .lic extension that contains the license information for your CUCM server. You need to copy this file to your CUCM server using a USB drive, FTP, or SCP.</li>


<li>Upload the license file to the CUCM administration page and apply it. After copying the license file to your CUCM server, you need to upload it to the CUCM administration page from a web browser. You can do this by going to System > Licensing > License File Upload, browsing for the license file, and clicking on Upload License File. You will see a message that confirms the upload of the license file.</li>


<li>Verify that your license is valid and that your CUCM is fully functional. After uploading the license file, you need to verify that your license is valid and that your CUCM is fully functional. You can do this by going to System > Licensing > License Unit Report, and checking the status of your DLUs and node licenses. You can also go to System > Licensing > License Unit Calculator, and checking if you have enough DLUs and node licenses for your devices and servers. You can also test your CUCM features and functions by making some calls, registering some devices, or using some applications.</li>


</ol>


<h4>How to troubleshoot common issues with CUCM 8.6.2 and keygen</h4>


<p>Even if you use a keygen to generate a license for CUCM 8.6.2, you may encounter some issues with it. Here are some common issues and their solutions:</p>


<ul>


<li>Issue 1: Database communication error when logging in to the CUCM admin web page from Publisher</li>


<li>Solution 1: Check the database replication status, restart the Cisco DB service, or reset the database replication from scratch</li>


<p>This issue may occur if the database replication between the Publisher and the Subscriber is broken or not configured properly. The database replication ensures that the data on both servers are synchronized and consistent. To check the database replication status, you can use the Real Time Monitoring Tool (RTMT) or the command line interface (CLI) of CUCM. You can find the detailed steps here. If the database replication status is not good, you can try to restart the Cisco DB service on both servers, or reset the database replication from scratch. You can find the detailed steps here.</p>


<li>Issue 2: Connection to the server cannot be established (certificate exception) when accessing the CUCM admin web page from Subscriber</li>


<li>Solution 2: Regenerate or import the self-signed certificates for tomcat, callmanager, and CAPF on both Publisher and Subscriber</li>


<p>This issue may occur if the self-signed certificates for tomcat, callmanager, and CAPF on both servers are expired, corrupted, or mismatched. These certificates are used to secure the communication between the web browser and the CUCM server, and between the CUCM servers themselves. To regenerate or import the self-signed certificates, you can use the Certificate Management page or the CLI of CUCM. You can find the detailed steps here.</p>


<li>Issue 3: License not valid or expired when applying the license file generated by keygen</li>


<li>Solution 3: Check the license file format, content, and checksum, or try another keygen program</li>


<p>This issue may occur if the license file generated by keygen is not compatible with CUCM 8.6.2, or if it has been tampered with or corrupted. The license file should have a .lic extension, and it should contain some information such as the MAC address of the server, the number of DLUs and node licenses, and the expiration date of the license. The license file should also have a checksum that verifies its integrity and authenticity. To check the license file format, content, and checksum, you can use a text editor or a checksum calculator. You can find some examples here. If the license file is not valid or expired, you can try to generate another one using a different keygen program.</p>


</ul>
