What's New in Release 11.6

IPv6

Cisco Jabber 11.6 is fully IPv6 ready, it works as normal in pure IPv6 and hybrid networks, subject to a number of limitations (for more information see the Planning Guide for Cisco Jabber 11.6. Cisco Collaboration solutions does not currently fully support IPv6. For example, Cisco VCS Expressway for Mobile and Remote Access has limitations in pure IPv6 networks that require NAT64/DNS64 to be deployed in mobile carrier networks. Cisco Unified Communications Manager and Cisco Unified Communications Manager IM and Presence Service don't currently support HTTPS in pure IPv6 networks.

IPv6 is configured using the IP_Mode parameter to set the protocol to IPv4, IPv6, or dual stack. Dual stack is the default setting. The IP_Mode parameter can be included in the jabber-config.xml file, the bootstrap for Windows, and the URL configuration for Mac and Mobile clients.

The network IP protocol used by Jabber when connecting to services is determined by the following factors:

• The jabber-config.xml IP_Mode parameter.

• The client operating system IP capabilities.

• The server operating system IP capabilities.

• The availability of a DNS record for IPv4 and IPv6.

• Cisco Unified Communications Manager SIP setting for softphone devices configuration for IPv4, IPv6, or both. The SIP connection setting for softphone devices must match the Jabber IP_Mode parameter setting to make a successful connection.

• Underlying network IP capabilities.

On Cisco Unified Communications Manager, the IP capability is determined by generic server settings and device-specific settings.

When you use Jabber in IPv6_only mode, NAT64/DNS64 is required to connect to an IPv4 infrastructure. For example, when connecting to Cisco WebEx Messenger service, Cisco VCS Expressway for Mobile and Remote Access, and Cisco Spark.

For more information about the IP_Mode parameter, see the Parameters Reference Guide for Cisco Jabber 11.6. For more information about IPv6 support, see the Planning Guide for Cisco Jabber 11.6.

Cisco Jabber Diagnostics Tool

The Cisco Jabber Diagnostics Tool provides configuration and diagnostics information for the following functionality:

• Service Discovery

• WebEx

• Cisco Unified Communications Manager Summary

• Cisco Unified Communications Manager Configuration

• Voicemail

• Certificate Validation

• Active Directory

• DNS Records

To access the Cisco Jabber Diagnostics Tool window, users must bring the hub window into focus and enter Ctrl + Shift + D. Users can update the data by clicking the Reload button. Users can also save the information to an HTML file by clicking the Save button.

The Cisco Jabber Diagnostics Tool is available by default. To disable this tool, set the DIAGNOSTICS_TOOL_ENABLED installation parameter to FALSE. For more information about this installation parameter, see On-Premise Deployment for Cisco Jabber 11.6, or Cloud and Hybrid Deployments for Cisco Jabber 11.6, depending on your setup.

New Configuration for Meeting Notifications

The DisableNonAcceptMeetingReminder parameter determines whether the Cisco Jabber popup meeting notification is displayed for nonaccepted WebEx Meetings. The default value is false, which means that the Jabber popup meeting notification displays for nonaccepted WebEx Meetings.

For more information about this parameter, see the Parameters Reference Guide for Cisco Jabber 11.6.

User Interface Updates

Presence pills and avatars have been redesigned and now have a round shape. Accessibility icons have also been redesigned. For more information about accessibility icons, see the Cisco Jabber for Windows 11.6 User Guide.

Limitations and Restrictions

Limitations and Restrictions for All Deployments

IBM Notes Contact Search

Jabber doesn't support searching for IBM Notes contacts using " or \ as the first character in the search string.

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)

The Cisco Jabber for Windows Meetings Service no longer supports automatic detection of proxy settings. Web Proxy Auto-Discovery (WPAD) protocol lookup is supported only for iOS devices. 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 are transferring a call to a third party, the third party must respond to the call before you can complete the transfer. You cannot currently dial the third party and connect the first party while waiting for the call to connect (also known as a blind transfer).

Chat Reply and No Voicemail Profile

The chat reply feature does not work if the user has no voicemail profile configured. If the user selects Chat reply in an incoming call, the call continues to ring and the Chat reply and Answer options are greyed out. This limitation is documented in CSCux75667.

Check Point VPN

Cisco Jabber for Windows does not currently support Check Point VPN. This limitation is documented in CSCuy34099.

Cisco AnyConnect Secure Mobility Client

Cisco Jabber for Windows supports Cisco AnyConnect Secure Mobility Client version 4.0 and later. This limitation is documented in CSCuy14721.

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 does not support Cisco Unity Connection dispatch messages. This limitation is documented in CSCuw31908.

Emails to a Group of Contacts

There is a limit of 2083 characters in the To field when sending an email to a group of contacts. Depending on the length of the email addresses and the number of contacts, 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. This limitation is documented in CSCuz80198.

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 will now not work for newly added domain users. Users in the initial domain are unaffected. This limitation is documented in CSCuu76519.

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). This item is documented in CSCuo57172.

Phone Mode Deployments with Microsoft Lync

Click-to-x functionality must be disabled 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 is not supported. This limitation is documented in CSCuz19139.

SAML Single Sign-On Limitations

When configuring SAML SSO on Cisco Unified Communications Manager and Cisco Unity Connection 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 is not valid. The requirement to use an FQDN is because the embedded Internet Explorer browser is not able to validate IP addresses in the Subject Alternate Name (SAN) certificate.

Space Characters in Credentials

The following rules apply to space characters and credentials:

• Usernames can contain spaces in on-premises deployments.
• Usernames cannot contain spaces in cloud-based deployments.
• Passwords cannot 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 does not currently support CTI connections over transport layer security (TLS). As a result, Cisco Jabber for Windows users cannot 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.

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.

Windows 10 Taskbar

On Windows 10 Build 10240, the Cisco Jabber presence and sign out taskbar actions don't work.

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 (~)

Limitations and Restrictions for On-Premises Deployments

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.

Limitations and Restrictions for Cloud Deployments

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 knowledge base article https:/​/​cisco-support.webex.com/​guest/​articles/​en_US/​Troubleshooting/​WBX000019555/​myr=false

Performance and Behavior Notes

Jabber to Jabber Calls and Symantec Host IDS (HIDS)

Jabber to Jabber calls can trigger errors in Symantec HIDS.

Symantec HIDS has a rule that disables connections from internet-based servers if it receives 5 connection requests from the same internet-based server within 200 seconds. For example, 3 Jabber to Jabber calls within 200 seconds will trigger Symantec HIDS. When this happens, ongoing Jabber to Jabber calls are dropped and Jabber to Jabber calls are disabled for 600 seconds.

To avoid this scenario, you must add Cisco Jabber to the Symantec exception list. This behavior is documented in CSCuw32007.

Meeting Reminders

Cisco Jabber displays pop-up reminders for Cisco WebEx meetings only. Reminders for non-Cisco WebEx meetings are not displayed.

If the URL for a WebEx meeting is changed (for example, by URL filter software), attempts to join the meeting from the meeting reminder or from the Meetings tab fail. This behavior is documented in CSCux03658.

Removing Participants During Conference Calls

Users can only remove participants from a conference call when using the softphone(CSF) device for calls. Users can't remove participants from conference calls in desk phone control mode or using extend and connect.

Video Calls

The Start My Video button doesn't work immediately after a call connects. Users must wait approximately 6 seconds after the call starts before clicking the Start My Video button. This behavior is documented in CSCuz06415.

Caveats

Caveats describe unexpected behavior. The following sections describe how to obtain the latest information.

Bug Severity Levels

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

Severity Level	Description
1 Catastrophic	Reasonably common circumstances cause the entire system to fail, or a major subsystem to stop working, or other devices on the network to be disrupted. No workarounds exist.
2 Severe	Important functions are unusable and workarounds do not exist. Other functions and the rest of the network is operating normally.
3 Moderate	Failures occur in unusual circumstances, or minor features do not work at all, or other failures occur but low-impact workarounds exist. This is the highest level for documentation bugs.
