These release notes describe new features, requirements, restrictions, and caveats for both Unified Communications Manager and IM and Presence Service. These release notes are updated for every maintenance release but not for patches or hot fixes.
Unified Communications Manager, the call-processing component of the Cisco Unified
Communications System, extends enterprise telephony features and capabilities
to IP phones, media processing devices, voice-over-IP (VoIP) gateways, mobile
devices, and multimedia applications.
The IM and Presence Service collects information about user availability, such as whether users are using communications devices (for example, a phone) at a particular time. IM and Presence Service can also collect information about individual user communication capabilities, such as whether web collaboration or video conferencing is enabled. Applications such as Cisco Jabber and Unified Communications Manager use this information to improve productivity amongst employees, that is, to help employees connect with colleagues more efficiently and determine the most effective way for collaborative communication.
In the past, export licenses, government regulations, and import
restrictions have limited Cisco System's ability to supply Unified Communications Manager
and IM and Presence Service worldwide. Cisco has obtained an unrestricted US export classification to address this issue.
Be aware that after you install an unrestricted release, you can never
upgrade to a restricted version. You are not even allowed to fresh install a
restricted version on a system that contains an unrestricted version.
Before you install or upgrade either product, Cisco recommends that you review the Related Documentation for information about the documentation available.

Unified Communications Manager and
Make sure that you
install and configure Unified Communications Manager and IM and Presence
Service on a Cisco Media Convergence Server (MCS), a Cisco Unified Computing
System (UCS) server, a Cisco-approved HP server configuration, or a
Cisco-approved IBM server configuration. For information about which MCS and
UCS servers are compatible with this release of Unified Communications Manager
or IM and Presence Service, see the related compatibility matrix.
IM and Presence
Service installer checks for the presence of the DVD-ROM drive,
sufficient hard drive and memory sizes, and sufficient CPU type and speed.
IM and Presence Service supports bridge upgrades from
any of the following servers:
MCS-7845-H2-IPC1 (only if each of the two disks has less than 72
GB of storage space; otherwise it is fully supported)
bridge upgrade allows you to create a DRS backup on the discontinued hardware.
You can then restore the DRS backup on supported hardware after you complete a
fresh IM and Presence Service installation on the supported hardware. If you
attempt an upgrade on discontinued hardware, a warning appears on the interface
and on the CLI, informing you that
Communications Manager or
IM and Presence
Service supports only the functionality to create a DRS backup on
pre-9.0 Unified Communications Manager or IM and Presence Service runs on a
deprecated server, you can upgrade it by using the Bridge Upgrade procedure.
Uninterruptible Power Source
that you connect each Unified Communications Manager or IM and Presence Service
server to an uninterruptible power supply (UPS) to provide backup power and
protect your system against a power failure.
MCS-781x and MCS-782x servers are not connected to a UPS, they run a higher
risk of file corruption during power outages because any cached data is lost
during a power outage on these servers with drive write cache enabled (and no
internal RAID cache battery backup). To prevent such file system corruption,
you must connect these servers to a UPS.
Communications Manager and IM and Presence Service run on one of the servers

USB and APC 750VA XL USB is supported.
occurs through a single point-to-point USB connection. Serial and SNMP
connectivity to the UPS is not supported, and the USB connection must be point
to point (in other words, no USB hubs). Single- and dual-USB UPS models are
supported with the APC Smart-UPS 1500VA USB and APC 750VA XL USB. The feature
activates automatically during bootup if a connected UPS is detected.
can run the CLI command

Smart-UPS device and starts the monitoring service if it is not already
started. The CLI command also displays detected hardware, detected versions,
current power draw, remaining battery runtime, and other relevant status
integration feature is activated, graceful shutdown begins as soon as the
low-battery threshold is reached. Resumption or fluctuation of power will not
interrupt or cancel the shutdown, and administrators cannot stop the shutdown
after the integration feature is activated.
Unified Communications Manager or IM and Presence Service releases, MCS models,
or UPS models, you can cause an external script to monitor the UPS. When low
battery is detected, you can log in to the Unified Communications Manager or IM
and Presence Service server by using Secure Shell (SSH), access the CLI, and
