/mcpIM and Presence Service capabilities are included within both User Connect Licensing (UCL) and Cisco Unified Workspace Licensing (CUWL). IM and Presence Service capabilities can also be acquired for users that are not Unified Communications Manager IP Telephony users through the Jabber for Everyone Offer. For more information, see Jabber for Everyone Quick Start Guide. Required Installation Information When you install either Unified Communications Manager or the IM and Presence Service on a server, the installation process requires you to provide specific information. You can provide this information manually during the installation process or you can provide it using an answer file. For each server that you install in a cluster, you must gather this information before you begin the installation process. The following table lists the information that you must gather before you begin the installation. Because some of the fields are optional, they may not apply to your configuration. For example, if you decide not to set up an SMTP host during installation, the parameter still displays, but you do not need to enter a value. Note You cannot change some of the fields after the installation without reinstalling the software, so be sure to enter the values that you want. The last column in the table shows whether you can change a parameter after installation, and if you can, it provides the appropriate menu path or Command Line Interface (CLI) command. We recommend that you make copies of this table and record your entries for each server in a separate table, even if you are planning to use the DMABackupInfo.inf file to configure your system.
