Cisco® Unified Communications Manager is the heart of Cisco collaboration services, enabling session and call control for video, voice, messaging, mobility, instant messaging, and presence.

Product overview

Over the past year, remote work has seen accelerated adoption. Analysts predict that in years to come, work will be a blend of in the office and remote. Key to a successful hybrid work model is empowering the workforce with the same collaboration capabilities they get in the office, from any work location.

Telephony remains a critical part of doing business for many organizations and supporting remote work from a voice and unified communications perspective remains a top priority for Cisco.

Cisco® Unified Communications Manager (UCM) is the core of Cisco’s collaboration portfolio. UCM has a rich feature set that supports calling, mobility, conferencing, and messaging features. Release 14 of UCM extends the product with new features for remote workers.

UC Manager is the industry leader in enterprise call and session management platforms, with more than 300,000 customers worldwide, and more than 120 million Cisco IP phones and soft clients deployed.

What’s new with Cisco Unified Communications Manager Version 14

Release 14 is the latest feature release in market leading Cisco Unified Communication Manager. This release will further extend Cisco Unified Communication Manager’s leadership through features that enrich user experiences, simplify administration workloads, enhanced security and enhanced business and operational insights through Webex Cloud Connected UC services

Release 14 brings improved experience for users and administrators, including:

      Increased cluster capacity so that more devices can be supported without adding more resources

      Flexibility to move a registered phone from office to home without repeating the onboarding process

      Flexibility to move between Wi-Fi and LTE networks without dropping an existing call on
Cisco Webex® apps

      Operational workflow simplification by managing all certificates from a single portal

Table 1 lists major features in Cisco Unified Communications Manager Version 14

Table 1.        High-level features in UCM Version 14



Enhanced user experience

Call persistency – LTE to Wi-Fi support

  Flexibility for users on the Webex app to switch between networks without getting disconnected from active calls
  When Cisco UCM detects that a client has lost connection with it, the call is not impacted. If the client connects back within 12 seconds, media is resumed with the client's updated connection address on a new network
  This feature requires the Webex app

MRA registration failover support

  The Webex app or Jabber can quickly detect any outage in the registration path if Cisco Expressway-E/C or CUCM is down and can re-register over a different Expressway-E/C path to CUCM
  Expressway-E/C uses adaptive routing to find the most optimal path to CUCM

UDS optimization for bulk search and high availability

  UDS is enhanced to perform better discovery of the home cluster of a user across remote clusters. This helps in avoiding the Cisco Jabber login failures and ensures geographical redundancy in the event of a data center failure or shutdown.
  The UDS bulk search by email enables Cisco Jabber to send requests in batches using the email attribute to prevent high CPU usage by UDS and Cisco Tomcat services.

AV1 codec support

  AV1 codec enables users joining meetings on low bandwidth to get same video quality as users with normal bandwidth. With this release CUCM 14 is AV1 codec ready. A Webex room device registered to CUCM can

Bidirectional presence sync between Webex app and desk phone

  A user’s shared IP phone device off-hook/on-hook status is integrated with the user’s Webex app presence
  When a user sets status as Do Not Disturb (DND) on the Webex app, the user’s IP phone status is set to DND
  Requires CUCM to be onboarded to Webex Cloud Connected UC (service release date will be announced later)
  Also supported with CUCM 12.5 SU4 and later

Headset-based Extension Mobility login

  Enables user to login or logout of Cisco Extension Mobility service with the user’s paired Cisco headset

Cisco Jabber® IM&P high availability with zero down time

  Significantly reduces downtime for Jabber user during server failover, fallback, and upgrades
  Requires Cisco Jabber release 14

Phone presence in centralized IM&P

  User’s phone presence is updated from CUCM to centralized IM&P in centralized deployments. There is no dependency on user having logged into Jabber
  Reflects correct phone presence for shared lines

Jabber out of office presence support

  When a user is Out Of Office (OOO), you can let others know through Cisco Jabber presence status. Requires Cisco Jabber release 14

Simplified administration

Cluster scale

  Enables lower deployment cost through a 25 percent increase in cluster scale. A standard cluster now supports registration of 50,000 devices, and a mega cluster supports registration of 100,000 devices.

Extension Mobility cross-cluster (EMCC) scale

  Enables enterprises to deploy EMCC for more users by supporting 7500 user logins. The login rate is increased from 90 to 150 per minute on a 10,000-user OVA.

High availability proxy and Tomcat restructuring

  Increases WebApp stability
  Restart individual Tomcat container/instances without impacting other web apps
  Faster startup time of web apps
  Better serviceability with new RTMT counters for monitoring a WebApp session

Fresh install with data import

  UCM-native virtual-to-virtual migration functionality, avoiding a refresh upgrade and external tool requirements
  Fast migration and major version skipping with less downtime than direct refresh upgrades and no need for a separate management app
  All-in-one solution for “repave” scenarios where the site, hardware, IP, and/or version need to change

Simple phone refresh

  Easy, intuitive Cisco IP phone migration solution native to Unified Communications Manager. It minimizes the cost and complexity of replacing deprecated or faulty phones.
  End user or an administrator can easily migrate all the settings from an old phone to a new phone with a simple user interface

Flexible infrastructure support

  VMware ESXi 7.0 and 6.7 support
  More flexibility with virtual machine configurations and CPU minimum hardware requirements
  Easier to accommodate customer hardware standards and operations
  Easier to adjust resources to scale or to improve performance, without hardware restructuring or UCM reinstallations

GUI banner ads to give notice of ungraceful shutdown

  A UI alert is triggered, and an administrator is notified when a system rebuild or upgrade is required

PCD Release 14 improvements

  Configurable performance parameter to more efficiently handle deployments with a very high numbers of nodes, clusters, and/or tasks
  Usability improvements

Jabber location migration support

  Jabber location can be migrated from one cluster to another using BAT. Useful in migration from standard deployment to centralized deployment

Security and compliance

Accessibility for self-care portal

  The self-care portal is enhanced with the following accessibility improvements:
  Font type and size – consistent usage of a sans-serif font type with a minimum DPX size of 10 across the portal
  Keyboard navigation – better navigation for support pages under Phones>My Phones
  Screen reader and compatibility – easy-to-view content and navigation for screen reader users

Simple phone security with SIP OAuth support for Cisco IP Phone 7800 and 8800 Series

    Privacy and data security

    Vulnerability management

    Cryptographic support (X.509)

Emergency 911 (E911) regulatory compliance

  Cisco UCM software, when installed using a United States time zone, proactively checks for the presence of a direct 911 dial pattern, creates it, and notifies an administrator to perform the required configuration or waive it where E911 regulatory laws are not applicable.
  Cisco Emergency Responder provides advanced emergency calling to Unified Communications Manager. It assures that UCM will send emergency calls to the appropriate Public Safety Answering Point (PSAP) for a caller's location, and that the PSAP can identify the caller's location and return the call if necessary. In addition, it provides local onsite notification through several methods, including phone alert, web portal alert, email, and text alert. Deploying this capability helps ensure compliance. (See for more details.)
