Modern Design

We improved the user experience in this release with a new Modern Design. The Modern Design features a single-window UI. Jabber defaults to the Modern Design in all deployments. Users in on-premises and Webex Messenger deployments can choose to use the Classic Design.

Jabber Team Messaging Mode only supports the Modern Design view. Users cannot choose the Classic Design in Jabber Team Messaging Mode.

If you want your on-premises or Webex Messenger deployment to default to the Classic Design, you can set the default with the UXModel parameter. The allowed values are Modern (the default) and Classic. Each user's preference takes precedence over this parameter. For details, see the Parameters Reference Guide for Cisco Jabber.

Users can also customize their app by choosing their preferred design in Settings > Appearances.

Themes

We have added themes for the Jabber app. The available themes are:

• Default

• Dark

  Note	We don't support changing the color of chat text in this theme.

• High Contrast

Users can switch between the available themes through Settings > Appearances.

Improved Prompts for Office 365 Migration

After administrators migrate user accounts to Office 365, users that use Save Chats to Outlook, will receive a message that the account has been migrated and prompted to resubmit their credentials in order to continue using this feature.

Accessibility Improvements

We made accessibility improvements throughout the client, including the following:

• Screen reader support

  • Improved the accessibility text for screen readers.

  • Improved keyboard navigation of the chat history.

  • Improved control labels.

  • The information panel announces the currently selected contact or the person with whom you are communicating.

  • The titles of detached conversations include the contact's name.

• Visual improvements

  • Added a high contrast theme which improves the color contrast and supports larger font sizes.

• New shortcut keys

  • Ctrl + Shift + M—Places focus on the screen share button. You can then choose to stop the share or share a different application.

  • Ctrl + Shift + N—Provides access to notification messages. This permits keyboard users to answer or decline a call, join meetings, and manage new locations.

Call Progress Indicator for Extend & Connect

When a user makes an outbound call with Extend & Connect, a call window now appears immediately after dialing. If the user does not answer on their mobile device, the call terminates after receiving a PSTN timeout signal.

Chat Rooms Maintains Participant List Visibility

We changed participant list behavior for group chats and chat rooms in on-premises and Webex Messenger deployments. Now, when you switch from one chat room to another chat room, it maintains the visibility of the participant list. If you open the participant list in Chat A and then switch to Chat B, the participant list is visible when you return to Chat A.

Person-to-person chats do not behave this way.

Display Tab Labels

By default in Release 12.6, the client didn't display tab labels in the hub window. Users can enable tab labels through their preferences.

If you want to change the default behavior for displaying tabs, use the new ShowTabLabel parameter. Each user's preference takes precedence over this parameter. For details, see the Parameters Reference Guide for Cisco Jabber.

Configure Clients Through Cisco Webex Control Hub

You can run Jabber Team Messaging Mode in IM-Only Mode which doesn't need Cisco Unified Communications Manager and its calling capabilities. To replace Unified CM as the deployment site for the Jabber configuration file, you can upload your Jabber configuration file to the Control Hub. You can upload one configuration file for each organization.

Go to Services, then select the Message card, and choose Settings. Then, select Upload Configuration File. The file must be in .xml format.

If you have Jabber configuration files in both the Control Hub and Unified CM, the value of a parameter from the Unified CM takes precedence.

People Insights

People Insights provides Jabber Team Message Mode users with professional profiles of their contacts. Anywhere a contact card appears, user can access People Insights: contact lists, in conversations, from the call history, and voicemail history.

The feature only displays publicly available information in profiles, and internal company directory information to users in the same company. This internal directory information is not visible to users outside the company. Users can edit their own profiles to add more data. For more information, see What Is People Insights.

To enable People Insights, go to the Control Hub, and select Settings > Directory Synchronization and People Insights and turn on the Show People Insights toggle.

Do Not Disturb Setting

We changed the intervals in the Do Not Disturb setting to 30 minutes, 1 hour, 2 hours, 4 hours, 8 hours, and 24 hours.

Presence Based on Non-Jabber Activity

In previous releases, Jabber team messaging mode reported users presence based only on their activity in the Jabber app. Jabber now reports your presence based on activity across your computer.

Enterprise Content Management (ECM) Support

You can view, send, and receive ECM files. Upload ECM files from OneDrive or SharePoint Online, and send them via chat to other Jabber users who are authorized to view them. When users send attachments, they can choose to upload files from their computer or ECM account. Users can choose to send the files to other people in their organization, or to specific people who have access to the file. When the recipient gets the message with the ECM attachment, they'll need to be logged in to that ECM service before they can view or open the file.

For more information, see https://help.webex.com/en-us/nfia8at/Configure-Enterprise-Content-Management-Settings-in-Cisco-Webex-Control-Hub and https://help.webex.com/en-us/nuvy9lb/Enterprise-Content-Management-in-Cisco-Webex-Control-Hub.

Quote Message

You can add context to a message by quoting another message in the same space. To quote a message, hover the cursor over the message you want to quote and select Quote message. After you send the message, the quoted message appears above your message in the space.

BOT Support

BOTs now appear in your search results, and you can add them to spaces and to an existing conversation, and create a new conversion with a BOT . To find a BOT, go to the search bar and type the first few letters of its name. BOTs appear in their own category underneath results from your contacts and directory.

Jabber Team Messaging Mode users can search for and use BOTs that are deployed as part of the Webex Platform Service. You can find these BOTs on the Cisco Webex App Hub or develop your own for your users. BOTs from the Cisco Jabber BOT SDK work only for on-premises and Webex Messenger deployments.

Proxy Authentication Support

Earlier releases do not support proxy authentication. Jabber now supports proxy authentication as outlined in this table:

For information on Proxy Auto-Config (PAC) files, see https://www.cisco.com/c/en/us/td/docs/security/web_security/connector/connector2972/PACAP.html.

If you deploy a TLS-inspecting proxy, install a CA certificate into the OS of the device with a trust chain that allows a successful certificate validation.

Jabber validates the certificates of the systems with which it communicates. Jabber validates the certificates for a TLS session against the list of trusted root certificate authorities in the other system's OS. Jabber also checks the certificates against known malicious or compromised certificate authorities.

On-Demand Recording

In previous releases, you could only enable or disable recording for all calls in Jabber. On-demand recording gives you the option to enable users to selectively record calls over Jabber's Built-In Bridge (BiB). When you enable this feature, the call control menu includes a Record option for the user to start and stop recording at any time.

You need Cisco Unified Communications Manager Release 12.5(1) to support this feature.

For information on using on-demand recording, see the Feature Configuration for Cisco Jabber guide.

You can force all recording to occur on the Jabber BiB with the Prefer_BIB_recorder parameter. For details, see the Parameters Reference Guide for Cisco Jabber.

Application Sharing

When you share your screen during a call, CMR meeting call, or CMS meeting call, you can limit what you share to a specific application, instead of sharing the entire screen. Now, from the Share Screen, you have the option of choosing which application to share.

Updates to Collaboration Meeting Room Controls

This release includes several new CMR controls. Hosts can now:

• Mute or unmute all participants

• Pause and resume the meeting recording

All participants can do the following:

• Start or stop sending video

• Copy the meeting link

• Use the Meeting Info icon to display details about the meeting

Voicemail Improvements

We improved the voicemail capabilities in the desktop clients.

Users can create voicemails without making a call and then send the voicemail to one or more contacts. The voicemail server's administrator can also create distribution lists to which users can send voicemails. Users can select recipients from the voicemail server's catalog.

Users can directly reply to the sender of a voicemail or to all recipients of that message. Users can also forward voicemails to new recipients.

Display Directory Number or Label for Single Lines

In multiline operation, users choose between their configured lines in a selection list. The selection list displays the directory number or the label for each line. In earlier releases, the selection list does not appear for users who only have a single line.

Now, for Phone-Only Mode and Phone Mode with Contacts deployments, the single line's number or label appears by default. For Full UC Mode deployments, the single line's number or label is hidden by default.

You can override the default behavior for single-line operation with the new SingleLinePhoneLabel parameter. For details, see the Parameters Reference Guide for Cisco Jabber.

Multiline Improvements

In earlier releases, Jabber has these multiline limitations:

• CTI-enabled users can only control the primary line on their desk phone.

• You couldn't configure two lines with the same number that are associated with different partitions.

As of Release 12.7, users can control all lines on their desk phone. You can also configure two lines with the same number that are associated with different partitions.

Enhancement to Security Labels

We enhanced our support for security labels, based on the XEP-0258 standard, for instant messages. The InstantMessageLabels parameter now supports <label> elements. You can assign more metadata to the security labels. You can use the <label> element to identify the security compliance server, such as Apache NiFi, that screens the messages before delivery.

For more information about using the InstantMessageLabels parameter, see the Parameters Reference Guide for Cisco Jabber. You can configure this setting in the Unified CM Administration or in the jabber-config.xml configuration file.

For information on using security labels in your deployment, see the Feature Configuration for Cisco Jabber guide.

Updated Sign-Out Behavior

If users sign out of Jabber, they must now re-authenticate when they next sign in.

Users do not have to re-authenticate in these cases:

• A configuration change requires them to sign out.

• They kill the Jabber app and restart it. (For desktop users, this includes when you choose Exit Jabber.)

• Mobile Jabber users with touch, fingerprint, or face ID enabled.

OAuth Handling of Refresh Tokens

If you have OAuth enabled in your deployment, Jabber now checks, by default, for expired refresh tokens when users sign in. If a refresh token has expired, the user must re-authenticate. If the refresh token expires while a user is signed in, Jabber signs them out with a message that their session expired.

The LegacyOAuthLogout parameter controls this behavior. The default value of false checks for expired refresh tokens. If you set the value to true, Jabber never checks for expired refresh tokens. For details, see the Parameters Reference Guide for Cisco Jabber.

You can install Cisco Jabber for Windows on the following operating systems:

• Microsoft Windows 10 (desktop mode)

• Microsoft Windows 8.1 (desktop mode)

• Microsoft Windows 8 (desktop mode)

Cisco Jabber for Windows does not require the Microsoft .NET Framework or any Java modules.

Windows 10 Servicing Options

Cisco Jabber for Windows supports the following Windows 10 servicing options:

• Current Branch (CB)

• Current Branch for Business (CBB)

• Long-Term Servicing Branch (LTSB)—with this option, it is your responsibility to ensure that any relevant service updates are deployed.

For more information about Windows 10 servicing options, see the following Microsoft documentation:https://technet.microsoft.com/en-us/library/mt598226(v=vs.85).aspx.

Note

Cisco Jabber installs the required files to the following directories by default: %temp%\Cisco Systems\Cisco Jabber-Bootstrap.properties file and installation log %LOCALAPPDATA%\Cisco\Unified Communications-Logs and temporary telemetry data %APPDATA%\Cisco\Unified Communications-Cached configurations and account credentials %ProgramFiles%\Cisco Systems\Cisco Jabber-Installation files for x86 Windows %ProgramFiles(x86)%\Cisco Systems\Cisco Jabber-Installation files for x64 Windows

LDAP Credential Delivery with Unified Communications Manager 12.5(1) SU2

In Unified Communications Manager Release 12.5(1) SU2, Unified CM added support for securely passing encrypted LDAP credentials in the Service Profile. This update secures access to your directory by ensuring that the password is always stored and sent in an encrypted format. This change includes encryption during directory access authentication, client configuration file downloads, BAT imports/exports, and upgrades.

In Jabber 12.8 with this Unified CM release or later, we take advantage of this capability by downloading the LDAP credentials as part of User Profile after end-user authentication.

In Jabber 12.7 and earlier with this Unified CM release or later, we can’t use these credentials from the Service Profile as we did before. They pass an encrypted password to Active Directory which causes a connection failure. For these Jabber releases with the upgraded Unified CM, provide the LDAP credentials through the jabber-config.xml file.

For more details, see the Release Notes for Cisco Unified Communications Manager and the IM and Presence Service, Release 12.5(1) SU2 and the section on LDAP Service Accounts in the Planning Guide for Cisco Jabber.

Device Name with Extension Mobility

When Extension Mobility is enabled, the controlled devices menu in Jabber displays the phone type only, instead of the phone type and user name.

Cisco IP Communicator

Cisco IP Communicator isn’t supported as a controlled device on Jabber when users choose to use their desk phone for calls.

Multiline

Cisco Jabber doesn't support configuration of two lines with same number associated with different partitions.

Allow Paste Operations via Script

Jabber versions 11.8.5 and later may have issues with Copy/Paste when the policy Allow paste operations via script is enabled for Internet Explorer at Windows Components > Internet Explorer > Internet Control Panel > Security Page > Internet zone.

Single Number Reach

For Cisco TelePresence Video Communication Server Control (VCS) versions earlier than 8.10.X, configure the editable inbound rules to enable the single number reach for users who are using Cisco Jabber over Mobile and Remote Access. For more information, see Limitations in Enable Single Number Reach section from the Feature Configuration Guide for Cisco Jabber 12.0.

Voicemail Credential Popup during Sign-in

In a hybrid deployment, if Webex messenger, Call Manager and Unity connection are all SSO enabled, and voicemail credentials have been previously saved to cloud, users may see the Update Credentials popup for voicemail during the sign-in process. The workaround is not to configure voicemail server address on the cloud server but only configure it in the service profile or the jabber-config.xml file.

IBM Notes Contact Search

When searching for an IBM Notes contact, entering either " or \ as the first character in the search string won't find the correct contact.

Real-Time Transport Control Protocol (RTCP)

Jabber sends RTCP packets even when disabled. RTCP is an integral component of Jabber Telephony services.

Cannot Copy Image

You can’t right-click over an image in a conversation in Jabber and select copy. Instead, highlight the image and then right-click to copy it.

Microsoft Outlook OST File

Intermittently Cisco Jabber for Windows is unable to access the Microsoft Outlook OST file. To resolve this issue, restart Jabber and restart Outlook.

Automatic Detection of Proxy Settings (WPAD)

Cisco Jabber doesn’t support Web Proxy Auto-Discovery (WPAD) proxy discovery. For information about how to configure proxy settings for Cisco Jabber, see Configure Proxy Settings in the On-Premises Deployment for Cisco Jabber guide.

Call Transfers

When you’re transferring a call to a third party, the third party must respond to the call before you can complete the transfer. You can’t currently dial the third party and connect the first party while waiting for the call to connect (also known as a blind transfer).

Prior to Release 12.7(1), Cisco Jabber doesn’t correctly inform Unified Communications Manager that a call being transferred is on hold. This behavior results in incorrect reporting when you use Jabber with Cisco Finesse.

Chat Reply and No Voicemail Profile

If the user has no voicemail profile configured, the chat reply feature doesn’t work. If the user selects Chat reply in an incoming call, the call continues to ring and the Chat reply and Answer options are grayed out. CSCux75667 documents this limitation.

Cisco AnyConnect Secure Mobility Client

Cisco Jabber for Windows supports Cisco AnyConnect Secure Mobility Client version 4.0 and later. CSCuy14721 documents this limitation.

Cisco Unity Connection Dispatch Messages

In Cisco Unity Connection, a dispatch message is sent to a distribution list with the message configured in such a way that only one user responds to that message. A user can accept, decline, or postpone the dispatch message. Cisco Jabber for Windows doesn’t support Cisco Unity Connection dispatch messages. CSCuw31908 documents this limitation..

Emails to a Group of Contacts

There’s a limit of 2083 characters in the To field when sending an email to a group of contacts. With long email addresses or many recipients, not all contacts may be added to the email. For more information about the 2083 character limitation, see https://support.microsoft.com/en-ie/kb/208427.

Location Feature and Multiple Domain Support

Consider the following deployment scenario:

When you deployed your Cisco Unified Communications Manager IM and Presence Service node, all users were imported with single domain support. You later changed the address scheme to Directory URI (multiple domain support).

The location feature now doesn't work for newly added domain users. Users in the initial domain are unaffected. CSCuu63734 documents this limitation.

Logitech Keyboard Display Changes

The built-in display for Logitech UC keyboard K725-C doesn’t display caller or device information on incoming calls. Instead, the Cisco logo is displayed.

Microsoft Outlook Local Contacts and Presence

Users' presence is unknown when the contact is manually added to contacts in Microsoft Outlook 2010 and 2013, when the contact is added to local (custom) contacts with an email address type of SMTP. To resolve this issue, delete the contact and add it again manually, ensuring the email address type is Exchange (EX). CSCuo57172 documents this limitation.

Phone Mode Deployments with Microsoft Lync

Disable Click-to-x functionality if you want to deploy Cisco Jabber for Windows in phone mode on the same computer as Microsoft Lync. See the Common Installation Arguments section of the Deployment Guide for more information about the CLICK2X installer switch.

Plantronics Accessories and Software

If you use Plantronics accessories for Cisco Jabber call management, and if you have Plantronics Hub installed, ensure that at least version 3.5 is installed. Download Plantronics Hub 3.5 from the Plantronics website.

Remote Desktop Control over Mobile and Remote Access

Remote desktop control over Mobile and Remote Access isn’t supported. This limitation is documented in CSCuz19139.

SAML Single Sign-On Limitations

When configuring SAML SSO on Cisco Unified Communications Manager servers, use a fully qualified domain name (FQDN) instead of an IP Address to define the server name. If you use an IP Address, the client displays a warning message that the certificate isn’t valid. The requirement to use an FQDN is because the embedded Internet Explorer browser isn’t able to validate IP addresses in the Subject Alternate Name (SAN) certificate.

For the same reason, when you configure SAML SSO on Cisco Unity Connection servers, use a fully qualified domain name (FQDN) in Cisco Unified Communications Manager Service Profile instead of an IP Address to define the server name. If you use an IP Address, the client displays a warning message that the certificate isn't valid.

Space Characters in Credentials

The following rules apply to space characters and credentials:

• Usernames can contain spaces in on-premises deployments.

• Usernames can’t contain spaces in cloud-based deployments.

• Passwords can’t contain spaces in any deployment scenario.

• The first and last characters of usernames in on-premises deployments must not be spaces. This rule is also true for usernames synchronized from a directory source.

Standard CTI Secure Connection User Group

Cisco Jabber for Windows doesn’t currently support CTI connections over transport layer security (TLS). As a result, Cisco Jabber for Windows users can’t switch from using a CSF device to using a desk phone device if they belong to the Standard CTI Secure Connection user group. This limitation is documented in CSCux83786.

.TIFF Images Not Supported

In this release, if users have a .tiff image as their avatar, then Jabber displays the default icon image instead. To use a personal avatar, users must upload an image in a supported format, such as jpg, bmp, or png.

Using Click-To-X Feature with Contacts in Microsoft Outlook

If you use UDS as a directory source, users can only use Click-To-X capabilities, such as Click-To-Call and Click-To-IM, to contact Microsoft Outlook users if they are already in the cache file. A cache file is created for someone if they are in the users' Cisco Jabber contacts list, or have a Cisco Jabber history created by the user previously searching, IMing, or calling them, or by leaving a voice message.

Supported Characters in a Cisco Jabber User ID/E-mail Address

The following characters are supported in a Cisco Jabber user ID/E-mail Address:

• Uppercase characters (A to Z)

• Lowercase characters (a to z)

• Numbers (0-9)

• Period (.)

• Hyphen (-)

• Underscore (_)

• Tilde (~)

Extension Mobility

Jabber doesn’t support the Cisco Extension Mobility Cross Cluster (EMCC) feature.

Bluetooth Connectivity Unsupported with Cisco Headset 56x

Cisco Jabber doesn’t support the use of Bluetooth with Model 56x Cisco headsets. You can use these headsets with a USB-C to USB connector cable.

Cisco Headset Support with Multiple VoIP Apps

If you use Cisco Jabber with a Cisco Headset, you can’t install any other VoIP app, such as Cisco Webex Teams or Skype for Business, on your computer.

Windows 10 Crash Using Cisco 700 Series Headsets

If you use Cisco 700 Series headsets, you might experience Windows OS crashes (Blue screen). This occurs on Windows 10 version 1803 and earlier versions. Update to a later version of Windows 10 to correct the problem.

Joining Meetings by Meeting Number

In deployments that use a Cisco Webex Meeting Server, you cannot use the meeting number when joining by Webex. Use the meeting URL instead.

Joining Webex Meetings from Jabber

Webex site disclaimers don't appear when you join Webex meetings from Jabber. This limitation applies whether joining from the meeting reminder popup, or by selecting Join in Webex in Jabber.

Port Contention Disrupts Sennheiser Plug-In

Call control with the Sennheiser plug-in uses port 8001 by default. If another application uses this port, it can cause issues.

As a workaround, you can change the EPOS SDK's PortNumber parameter to another port in the appropriate file:

• Windows—%LOCALAPPDATA%\Sennheiser\SDKCore\PDS\config.dat

• Mac—/Library/Application Support/Sennheiser/SenncomSDK/secomSFSDK.dat

Note	Consult Sennheiser for more information about these files.

Shut down Jabber before changing the port in the SDK. Then, restart Jabber after you change the port.

Adding Federated Contacts

When adding federated contacts, Cisco recommends that users add the federated contacts as company contacts (File > New > Contact), rather than as custom contacts. Adding federated contacts as custom contacts can cause intermittent presence issues. This issue is documented in CSCuz59060.

Creating and Configuring Devices for Users in Cisco Unified Communications Manager 11.0

If you are creating devices for users in Cisco Unified Communications Manager 11.0, you can now specify a key order as RSA Only, EC Only or EC Preferred, RSA Backup. However, the EC Only option is not currently supported by Cisco Jabber, and if you select it, the client will fail to connect to the server.

Multiple Resource Login

When a user signs in to multiple instances of the client at the same time, the chat feature behaves as follows in on-premises deployments (more on multiple resource login in Common Deployment Scenarios):

• Signing in on one client changes custom availability states to 'Available' on other clients.

• If you set the availability state from 'On a call' to another state while on a call, the availability state does not automatically change to 'On a call' for subsequent calls.

SIP Trunk for Phone Presence

From Release 11.5(3), you must configure a SIP trunk between Cisco Unified Communications Manager and IM and Presence Service if you want Cisco Jabber users to see phone presence. In previous releases, a SIP trunk was not required for phone presence. This limitation is documented in CSCuz85578.

Blocking Users in Enterprise Groups

Blocking users does not prevent a blocked user's status from being displayed if the blocked users are in a contact list as part of an enterprise group. For example, User A blocks User B. However, User A is in User B's contact list as part of an enterprise group. As a result, User B can view User A's availability status.

Invitees to Instant Webex Meetings

Invitees to instant Webex meetings must be provisioned with Webex accounts before they can join an instant Webex meeting. For example, User A has a Webex account and starts an instant Webex meeting from Cisco Jabber. Use A then invites User B, who does not have a Webex account, to the meeting. When User B clicks on the meeting link in Cisco Jabber, an error message is displayed and the user can't join the meeting. User B must be provisioned with a Webex account before attempting to join any instant Webex meetings. This limitation is documented in CSCux52068.

Jabber to Jabber Calls

We recommend running Internet Explorer 10 or greater while using the Jabber to Jabber calling feature. Using this feature with previous versions of Internet Explorer or with Internet Explorer in Compatibility Mode can cause issues with Cisco Jabber client login (non-SSO setup) or Jabber to Jabber calling capability (SSO setup).

Users in Common Identity

There is a known issue with signing into Cisco Jabber for some users who have migrated to Common Identity. If users receive an Incorrect user name or password error message when entering their username and password, see the following article, https://help.webex.com/en-us/yhq7pw/Reset-Forgotten-Password-in-Cisco-Jabber.

Known defects, or bugs, have a severity level that indicates the priority of the defect. These release notes include the following bug types:

• All severity level 1 or 2 bugs

• Significant severity level 3 bugs

• All customer-found bugs except severity level 6 enhancement requests
