Version and Description

Cisco Unity Connection 15SU3 is a cumulative update that incorporates all of the fixes and changes to Cisco Unity Connection version 15 — including the operating system and components shared by Cisco Unity Connection and Cisco Unified CM. It also incorporates additional changes that are specific to this service update.

To determine the full version number of the Cisco Unified Communications Operating System that is currently installed on the active partition, run the CLI show version active command.

Full version numbers include the build number (for example, 15.0.1.13900-61), the software versions listed on the download pages on Cisco.com are abbreviated version numbers (for example, 15SU3).

Do not refer to version numbers in any of the administration user interfaces because those versions apply to the interfaces themselves, not to the version installed on the active partition.

New and Changed Support or Functionality

This section contains all new and changed support or functionality for release 15SU3 and later.

The following changes also have been introduced in 15SU3:

  • Certificate Management Changes

  • IPSec DH Group Changes

  • Updates to Cipher Management Page

For more information, refer Release Notes for Cisco Unified Communications Manager and the IM and Presence Service Release 15SU3 available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/rel_notes/15/SU3/cucm_b_release-notes-for-cucm-imp-15su3.html


Note


The new locales for Unity Connection 15SU3 have been released and available on Download Software site at https://software.cisco.com/download/home/282421576/type.

Smart Receiver Transport

Smart Transport has been introduced as an enhanced transport mechanism for Smart Licensing, in addition to the existing Call Home transport mode. All new Cisco Unity Connection installations will only support Smart Transport for Smart Licensing functionality.

In case of an upgrade or migration, Cisco Unity Connection automatically switches to Smart Transport if the connection to the endpoint "smartreceiver.cisco.com" is successful. If the connection fails, Cisco Unity Connection falls back to the Call Home mode temporarily.

For more information, see the “Managing Licenses“ chapter of the Install, Upgrade, and Maintenance Guide for Cisco Unity Connection, Release 15, available at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/install_upgrade/guide/b_15cuciumg.html.

FIPS Compliance

From Release 15SU3 onwards:

  • The Cisco Unity Connection available is FIPS 140-3 compliant.

  • CiscoSSL has been upgraded to Cisco SSL 7.3, which is FIPS 140-3 compliant.

Installation Information

For instructions on downloading the service update, see the "Downloading Cisco Unity Connection Release 15SU3 Software" section.

For instructions on installing the service update on Cisco Unity Connection, see the “Upgrading Cisco Unity Connection” chapter of the Install, Upgrade, and Maintenance Guide for Cisco Unity Connection Release 15 at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/install_upgrade/guide/b_15cuciumg/b_15cuciumg_chapter_010.html.


Note


  • If you are performing an upgrade from a FIPS enabled Cisco Unity Connection release to Cisco Unity Connection 15SU3, make sure to follow the steps for regenerating certificates before using any pre-existing telephony integrations. To learn how to regenerate certificates, see the Regenerating Certificates for FIPS section of the "FIPS Compliance in Cisco Unity Connection" chapter of the Security Guide for Cisco Unity Connection Release 15 at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/security/guide/b_15cucsecx.html
  • In FIPS mode, it is mandatory to upgrade all nodes in the Networking to Release 15 SU2 or later to ensure smooth operation and avoid replication issues.

Downloading Cisco Unity Connection Release 15 Service Update 3 Software


Note


The service update files can be used to upgrade Cisco Unity Connection. The files can be downloaded from the Unity Connection downloads page.

Caution


With restricted and unrestricted versions of Cisco Unity Connection software now available, download software carefully. Upgrading a restricted version to an unrestricted version is supported, but future upgrades are then limited to unrestricted versions. Upgrading an unrestricted version to a restricted version is not supported. For more information on restricted and unrestricted versions of Unity Connection software, see the Downloading a VMware OVA Template for a Unity Connection 15 Virtual Machine of the Release Notes for Cisco Unity Connection Release 15 at http://www.cisco.com/c/en/us/support/unified-communications/unity-connection/products-release-notes-list.html.

Downloading Cisco Unity Connection Release 15 Service Update 3 Software

Procedure

Step 1

Sign in to a computer with a high-speed Internet Unity Connection, and go to the Voice and Unified Communications Downloads page at http://www.cisco.com/cisco/software/navigator.html?mdfid=280082558.

Note

 
To access the software download page, you must be signed in to Cisco.com as a registered user.

Step 2

In the tree control on the Downloads page, expand Products> Unified Communications> Unified Communications Applications> Messaging> Unity Connection, and select Unity Connection Version 15SU3.

Step 3

On the Select a Software Type page, select Cisco Unity Connection Updates.

Step 4

On the Select a Release page, select 15 SU3, and the download buttons appear on the right side of the page.

Step 5

Confirm that the computer you are using has sufficient hard-disk space for the downloaded files. (The download descriptions include file sizes.)

Step 6

Select the applicable download, then follow the on-screen prompts to complete the download, making note of the MD5 value.

Restricted version UCSInstall_CUC_15.0.1.13900-61.sgn.iso
Unrestricted version UCSInstall_CUC_UNRST_15.0.1.13900-61.sgn.iso

Note

 

The VOS version for above mentioned ISO is 15.0.1.13900-79.

Step 7

Use a checksum generator to confirm that the MD5 checksum matches the checksum that is listed on Cisco.com. If the values do not match, the downloaded files are damaged.

Caution

 
Do not attempt to use a damaged file to install software, or the results will be unpredictable. If the MD5 values do not match, download the file again until the value for the downloaded file matches the value listed on Cisco.com.

Free checksum tools are available on the Internet, for example, the Microsoft File Checksum Integrity Verifier utility. The utility is described in Microsoft Knowledge Base article 841290, Availability and Description of the File Checksum Integrity Verifier Utility. The KB article also includes a link for downloading the utility.

Step 8

If you are installing from a DVD, burn the DVD, noting the following considerations:

  • Choose the option to burn a disc image, not the option to copy files. Burning a disc image will extract the thousands of files from the .iso file and write them to a DVD, which is necessary for the files to be accessible for the installation.

  • Use the Joliet file system, which accommodates filenames up to 64 characters long.
  • If the disc-burning application that you are using includes an option to verify the contents of the burned disc, choose that option. This causes the application to compare the contents of the burned disc with the source files.

Step 9

Confirm that the DVD contains a large number of directories and files.

Step 10

Delete unnecessary files from the hard disk to free disk space, including the .iso file that you downloaded.


Reverting to the Unity Connection Version on the Inactive Partition

See the “Rollback of Unity Connection” section of the “Upgrading Cisco Unity Connection” chapter of the Install, Upgrade, and Maintenance Guide for Cisco Unity Connection Release 15 at https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/15/install_upgrade/guide/b_15cuciumg.html.

If a Unity Connection cluster is configured, revert to the previous version on the publisher server first, then on the subscriber server.
