New and Changed Features for Cisco WebEx Meetings Server Release 2.8

This section describes features that are new or changed in this release.

For a complete list of system requirements, see the Cisco WebEx Meetings Server Planning Guide and System Requirements Release 2.8. Visit http:/​/​www.cisco.com/​en/​US/​products/​ps12732/​prod_​installation_​guides_​list.html.

All supported features from Cisco WebEx Meetings Server (CWMS) Release 2.7 (including features added in Maintenance Releases) are supported in CWMS 2.8. The data sheet for Cisco WebEx Meetings Server provides an overview of the features and benefits of CWMS. Visit http:/​/​www.cisco.com/​en/​US/​prod/​collateral/​ps10352/​ps10362/​ps12732/​data_​sheet_​c78-717754.html.

Replace a Virtual Machine

With this feature, you can replace a virtual machine without having to rebuild the CWMS system from scratch. You can replace any virtual machine, which is part of a CWMS system, except the primary admin node. Therefore, you can recover a system when some nodes are beyond repair but the primary admin node is still functional.

Administration Dashboard Enhancement

The dashboard (administration home page) now displays links to information about the data centers.

Application Audit Log Enhancement

This release includes the following new configuration option for the Application Audit Log: Enable Meeting Audit Logs. After you enable this setting, the system writes additional logs for meetings to the Application Audit Log.

This setting is visible to and configurable by anyone assigned to the Auditor role. If the system does not have anyone assigned to the Auditor role, this setting is visible to and configurable by the following roles:

  • Administrator

  • SSO Administrator

  • LDAP Administrator

Backup Management

You can view system backups and select a backup to validate or to use for disaster recovery. You can also delete a selected backup.

Backup Now Button

Click Backup now to immediately start a backup of your system.

  • Once started, this action cannot be stopped.

  • Do not power down your system, reboot your system, or exit Maintenance Mode (if the system is in Maintenance Mode) until the backup process is complete.

  • Depending on your system, the backup process can take longer than an hour to complete.

  • You can monitor the status of the backup process on the Backup Management page.

Blast Dial Audio Announcements

To make joining a Blast Dial meeting faster and easier, you can bypass the requirement to press 1, 2, or 3 to join. You can also configure which prompts to play by choosing one of the following options:

  • Skip press 1 prompt: the attendee connects to the meeting directly. The prompt to enter 1,2, or 3 does not play. The pin setting remains the same as before and the welcome prompt plays.

  • Skip press 1 prompt with Skip the welcome message: the attendee connects to the meeting directly. The prompt to enter 1,2, or 3 does not play. The pin setting remains the same as before, but the welcome prompt does not play.

Delete Users

You can delete host and administrator accounts. When you delete an account, the user data, future meetings, and recurring meetings hosted by the user are also deleted. Past meetings are retained for 6 months, because they are required for reports, billing, licensing, and auditing.

Important:

For six months after deletion, a deleted user cannot use the address associated with the deleted account to attend any meetings on the system. To disable the ability to host meetings and still permit the user to attend meetings, set their account status to INACTIVE.

Export Selected Users

You can also search users by using filters and a search string. From the results, you can select one or more users to export to a comma-separated values (CSV) file. If you don't select any users, the exported CSV file contains all users that match your selected filters.

Improved Meeting Join Experience

When an attendee enables the Start my video in all meetings setting, the video for their meetings starts when they choose their audio connection. This feature starts audio and video at the same time.

If the Start my video in all meetings setting is not enabled, and WebEx detects a camera, the attendee can do one of the following:

  • To start video for the current meeting, select Start My Video.

  • To start video for the current and all subsequent meetings, select Start My Video in all Meetings.

Jabber Support

This release introduces support for Cisco Jabber Release 11.8.

Last Hosted Column

When you select the Permanent licensees or Temporary licensees filter on the Users tab, the system replaces the Session Type column with the Last Hosted column in the results. The Last Hosted column displays the date on which the corresponding user last hosted a meeting. If the date was more than six months earlier, the column displays 6+ months instead of the date.

Manage Recordings

As an administrator, you have limited access to all recordings on system, for file storage management purposes. You can list, search for, and delete recordings. An Auditor can only list and search for recordings.

Meeting hosts can delete their own recordings. To mitigate issues with accidental deletion, the system retains deleted recordings for six months.

New Parameter for Email Template Customization

This release introduces the %MeetingNumberNoSpaces% variable. This variable provides meeting number without spaces. The existing %MeetingNumber% variable provides the meeting number with spaces.

Restrict Meeting Access to Authenticated Users

Meeting hosts can set up internal meetings that require attendees to sign in with Single Sign On authentication. Hosts can also set up internal meetings that are available to invited users only.

You can configure custom tags to identify participants as either internal or external (guest) attendees. These tags also appear with the participants usernames in reports.

TLS Support

CWMS Release 2.8 supports TLS 1.1 and later; TLS 1.0 is not supported, with one exception. Client connections from CWMS to an SMTP server using TLS 1.0 are supported.

CWMS Release 2.8 supports Cisco Unified Communications Server Release 10.5.2 and later, up to 11.5, for secure teleconferencing.

Updated Browser Support

Windows:

  • Chrome 57.0.2987

  • Edge (on Windows 10)

  • Firefox 52.0.2

  • Internet Explorer 11.0.9600

Mac:

  • Chrome 57.0

  • Firefox 52.0.2

  • Safari 10.0.3

Validation of Backup Data

The system validates a backup by verifying that:

  • The directory exists.

  • The files are present.

  • The checksum is correct.

  • The folder is in CWMS storage.

WebEx Meeting Client Application

This release supports WebEx Meetings Application version 31.11.6.9 for Windows and Mac.

WebEx Network Recording Player

This release supports the following Cisco Network Recording Player versions:

  • Windows: 31.11.6.9

  • Mac: 31.0.0.1100

WebEx Productivity Tools

This release supports WebEx Productivity Tools version 2.82.7000.1174 for Windows.

Supported Upgrade Paths

This release of Cisco WebEx Meetings Server supports upgrades from release 1.x to 2.8. The following points apply:

  • An upgrade is defined as a replacement of the system to deploy major modifications that we made to the system.

  • An update is defined as an incremental modification of the system. Updates deploy fixes and minor improvements.

  • An update retains all data from the original system. An upgrade retains all data from the original system, except for the logs.

  • When upgrading, you cannot skip a major version of the software and go directly to a companion maintenance release (MR).

    For example, to upgrade from 1.5MR5 to a 2.8MR, upgrade from 1.5MR5 to 2.8 and then update to the 2.8MR.


Note

All updates require downtime. For Multi-data centers, you update both data centers simultaneously.


Caution

Do not click Restart for one data center until the update for the other is complete, and both display the Restart button. When you update from Release 2.5MR6 or later to 2.8, restarting one data center before the update is complete for the other breaks replication.

Use the following table to determine your upgrade path to Cisco WebEx Meetings Server Release 2.8.

Important:

You cannot change the audio encryption type (Audio Encrypted -AE/Audio Unencrypted -AU) for the system, during an upgrade or during an update. After deployment, the only way to change a system from one type of audio encryption to the other is to deploy a new system.

For more information, see the following documents:

Updating Your High-Availability System

For systems with an existing High Availability (HA) system already attached, the HA system automatically updates when you update the primary system. Ensure that all HA virtual machines are turned on and running before you start the update process.

To add a High Availability (HA) system to your primary system, first deploy the HA system. Then update the HA system to the same version as the primary system. The HA system restarts at the end of the update process. We recommend that you wait an extra 15 minutes after the restart, before you begin to add the HA system to the primary system.

http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-guides-list.html

Limitations and Restrictions

Audio-only Meetings

Under the following circumstances, a meeting can continue for more than the 24-hour maximum meeting duration:

  • All attendees for a regular WebEx meeting are dial in (audio-only).

  • No attendee starts the web portion of the meeting.

In this case, the meeting continues as long as one attendee remains in the conference. If all dial-in attendees disconnect from the conference, the meeting ends within 24 hours of the start time. The meeting ends immediately if the meeting ran past the scheduled end time.


Note

This scenario applies only to regular WebEx meetings joined only by dial-in participants. This scenario does not apply to Personal Conference Number (PCN) meetings, or to regular WebEx meetings joined by web participants.

Internet Reverse Proxy Removal

As part of the Internet Reverse Proxy (IRP) node removal process, the Admin virtual machine sends a remove message to the IRP server. The message removes the IRP server and therefore all external access to the system. The message is sent as clear text, and it is unauthenticated. Well-crafted malicious code could replicate this behavior and lead to a denial of service.

We recommend that you limit access to port 64616, on the IRP node, to the Admin virtual machine only.

Productivity Tools

EMC SourceOne

WebEx Productivity Tools does not support EMC SourceOne. Users of EMC SourceOne can experience performance issues.

Incompatible Versions

Each release of Cisco WebEx Meetings Server supports a specific version of the Cisco WebEx Productivity Tools client. Download the supported version of Productivity Tools from the Downloads link on your Cisco WebEx Meetings Server website. Using incompatible versions of these two applications can cause issues.

Recording Limitations

The maximum recording size, per recording, is 2.2 GB (existing system limit). For Multi-data Centers, ensure that there is sufficient storage capacity available for all data centers. The maximum number of recordings depends on your storage server capacity. You can estimate the required storage server size for a typical five-year period using the following formula:

Estimated hours of meetings that you expect to be recorded per day * 50-100 MB per hour of recording * five years * 24 hours per day * 365 days per year

There are no per-user storage limitations. The system stores recordings indefinitely until users delete them. To prevent important recordings from being accidentally deleted, there is no setting to enable the automatic deleting of recordings. The storage server retains recordings marked for deletion for up to six months. During that time, users can still archive the recordings to other media.

When you configure a storage server and check Record under Administration Dashboard > Settings > Meetings > Participant Privileges, the Record setting is a system-wide setting.

Session Types

A session type is a predefined bundle of features and options (a profile) that site administrators can customize and assign to users. The default session (meeting) type is the PRO session type. Because of the relationships between the PRO session type and the custom session types, we recommend that you do not modify the PRO session type. The best practice is to create a custom session type to modify.

SSO and Email Address Changes

With this release, the Identity Provider (IdP) server can use any unique and static Active Directory (AD) field as the NameID for SSO configuration. If you plan to use the email address change feature, the email AD field is not static. Change the mapping for the NameID field on the IdP server to a unique AD field other than email. If you do not plan to use the feature to change email addresses, there is no requirement to change the mapping for the NameID field.


Caution

If the NameID field is mapped to the email AD field and you change user email addresses, the system creates a new user account for each changed address.

If you plan to change the NameID field mapping from email to another field (such as EmployeeNumber), users must prepare for the change. After you update the NameID fields in AD, have the users log in to CWSM before you change the email addresses. Otherwise, when both the NameID and email address change, no attribute matches the CWMS profile. In this scenario, the existing profile loses the ablity to log into the system and the system creates a new profile.

Outlook synchronizes with the Exchange server once a day. If you change an existing user’s email address on the Exchange server, the change does not immediately propagate to Outlook. Until synchronization occurs, the system receives the user’s former email address and issues a notice that the user cannot be found. A delegate (proxy) user cannot schedule a meeting for the user, or identify them as an alternate host, until after Outlook synchronizes with the Exchange server.

Manually synchronizing the systems does not solve this issue. This limitation is not a CWMS issue; it is the result of Outlook and Exchange design.

See also About SSO Configuration.

Windows 10 and Edge Browser Restriction

The Edge browser (for Windows 10) does not support the playback of WebEx recordings.

Virtual Desktop Infrastructure

The following limitations and restrictions are known to affect virtual desktop infrastructure (VDI) environments.

  • Citrix XenDesktop and XenApp are the only desktop virtualization software supported for this release of Cisco WebEx Meetings Server.

  • An architectural limitation of the virtual desktop environment can affect video quality. The frame rate may be low, causing a suboptimal experience when sending video.

  • Some video files cannot be shared in a virtual desktop environment.

  • Remote Access and Access Anywhere are not supported in virtual desktop environments. The underlying Citrix platform removes the Remote Access and Access Anywhere agents after the operating system restarts.

Important Notes

CWMS Licensing

Multi-data Center Licensing

Multi-data Center (MDC) licensing is required to join data centers to a system. Each data center requires an MDC system license; a MDC system requires a minimum of two licenses, one for each data center. A Single-data Center (SDC) does not require a system license. See "About MDC Licensing" in the Cisco WebEx Meetings Server Administration Guide for your release: http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-guides-list.html.

Host Licensing

The way Host (user) licenses are counted changed significantly in release 2.5. A user can host a maximum of two simultaneous meetings, consuming only one license. Previously, a user that hosted multiple meetings consumed multiple licenses. A Host licenses is not required to schedule or attend a meeting. See "License Status of Users" in the Cisco WebEx Meetings Server Administration Guide for your release: http:/​/​www.cisco.com/​c/​en/​us/​support/​conferencing/​webex-meetings-server/​products-installation-guides-list.html.

Extended Capacity Licensing

The base deployment models are micro (50), small (250), medium (800) and large (2000). You can extend the capacity of a large deployment, from 2000 up to 4000 ports. You can reduce the capacity of an extended system deployment, down to the base large deployment of 2000 ports.

To extend or reduce the system capacity, you add or remove up to 3 extension units. Each extension unit adds up to 700 more ports, up to the maximum 4000 ports for the system. When you add 3 extension units, you double the system capacity by adding 700 + 700 + 600 ports.

To enable this feature, you require an Extended Capacity license.

Hypervisor Support

Cisco WebEx Meetings Server runs on VMware virtual machines.

  • Both VMware vSphere and VMware vCenter are required to deploy Cisco WebEx Meetings Server. Using the vSphere client, you deploy the Cisco WebEx Meetings Server OVA file on an ESXi host managed by vCenter.

  • Purchase VMware vSphere 5.0, 5.0 Update 1, 5.1, 5.5, or 6.0 for use as the hypervisor platform for Cisco WebEx Meetings Server.

    • Buy vSphere directly from Cisco on the GPL (Global Price List). Cisco is an approved VMware partner and distributor. This is convenient for those who want to purchase everything from a single vendor.

    • Purchase vSphere directly from VMware, through enterprise agreements you have directly with VMware.

  • Cisco WebEx Meetings Server does not support other hypervisors.

  • For more information about hypervisor requirements, see the Planning Guide and System Requirements for Cisco WebEx Meetings Server at http:/​/​www.cisco.com/​en/​US/​products/​ps12732/​prod_​installation_​guides_​list.html.

Support for 4096-bit Certificates

Cisco WebEx Meetings Server (CWMS) is hard-coded to use 2048-bit certificates for its SSL system certificate(s). Certificates can be either self-signed or signed by a private or public Certificate Authority (CA).

CWMS also supports the use of 4096-bit certificates when they are imported as

  • a Secure Teleconferencing Certificate,

  • an SMTP certificate,

  • an SSO IdP certificate, or

  • a part of an SSL system certificate bundle.

    Certificates imported as part of an SSL certificate bundle must be signed by a private or public CA.

About Using Self-Signed Certificates

We strongly recommend using a publicly signed certificate instead of the provided self-signed certificate. User’s browsers trust publicly signed certificates because the list of Root Certificate Authority certificates installed on the computer establishes trust.

For Multi-data Center systems using self-signed certificates, the user receives multiple certificate warnings and must trust and install all certificates to use the system.

When using self-signed certificates, some users might have difficulty joining meetings because browsers by default do not trust such certificates. Users are required to explicitly establish trust in this case before they can proceed to join a meeting on your site. Some users might not understand how to establish trust with such a certificate. Others might be prevented from doing so by administrative settings. Use publicly signed certificates whenever possible to provide the best user experience.

The User Guide provides more information about this issue for users. See the "Meeting Client Does Not Load" topic in the "Troubleshooting" chapter of the Cisco WebEx Meetings Server User Guide at http:/​/​www.cisco.com/​en/​US/​products/​ps12732/​products_​user_​guide_​list.html.

Supported Ciphers

Cisco WebEx Meetings Server supports the following ciphers:

TLS Version 1.1

  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (secp256r1)

  • TLS_RSA_WITH_AES_128_CBC_SHA (rsa 2048)

TLS Version 1.2

  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (secp256r1)

  • TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA256 (secp256r1)

  • TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256 (secp256r1)

  • TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (secp256r1)

  • TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (secp256r1)

  • TLS_RSA_WITH_AES_128_CBC_SHA (rsa 2048)

  • TLS_RSA_WITH_AES_128_CBC_SHA256 (rsa 2048)

  • TLS_RSA_WITH_AES_128_GCM_SHA256 (rsa 2048)

  • TLS_RSA_WITH_AES_256_CBC_SHA256 (rsa 2048)

  • TLS_RSA_WITH_AES_256_GCM_SHA384 (rsa 2048)

About SSO Configuration

This release supports using any unique Active Directory (AD) field as NameID for SSO configuration. We recommend following AD attributes for NameID for SSO configuration:

  • Email

  • SAMAccountName

  • UserPrincipalName (UPN)

  • TelephoneNumber

  • EmployeeNumber

  • ObjectSid

Mandatory SAML Assertion Attributes

The following SAML assertion attributes are required for the Auto Account Creation feature:

  • lastname

  • firstname

  • email

    Important:

    The email attribute is always required, even if Auto Account Creation and Auto Account Update are disabled in the SSO configuration.

Expanding Your System

If you have VMware snapshots on your existing (pre-expansion) system, remove them before beginning the expansion.

System expansion requires Virtual Machine Disk (VMDK) attaching, from the original system to the target (expanded) system. If you leave snapshots on the original system and attach it to the target system, the target system won't power on because of snapshot inconsistency.

Productivity Tools Upgrade Notice

If a previously deployed Productivity Tools package has a different version or build number from a newly deployed Productivity Tools package and the upgrade is not blocked, your Productivity Tools client will notify you with an upgrade warning dialog box.

SNMP v2 Community Names

There is no default SNMP v2 community name entry in this release of Cisco WebEx Meetings Server. The system will remove the existing Cisco WebEx Meetings Server 1.0 default Community Name, "CWS-Public," after upgrading. Only user-added SNMP v2 community names are maintained.

Known Issues and Notices

Translated Documentation

Translated documentation for this release of Cisco WebEx Meetings Server is published 4–6 weeks after the English-language release.

Apple iOS 6.x and SSO

There is a known issue with Apple iOS 6.x. Single sign-on (SSO) does not work for internal users of iPad/iPhone who are using the Safari 6 web browser. An Apple defect that is fixed in iOS 7 caused this issue. The Safari bug ID is 13484525.

Keeping Your Hostname While Changing Your Virtual Machine IP Address

Never change the DNS entries for the hostnames that are configured in your deployment. You can change the hostname of a virtual machine that is part of your deployment. The corresponding IP address is picked up automatically from the DNS. To change the IP address of a virtual machine and keep the same hostname, perform the following steps:

  1. Configure a temporary hostname in the DNS.

  2. Change the hostname of the virtual machine to the temporary hostname that you configured.

  3. Take the system out of maintenance mode for the new hostname change to take effect.

    Your original hostname is not part of the deployment after this change.

  4. Change the IP address of the original hostname in the DNS to the new IP address.

  5. Change the temporary hostname of the virtual machine to the original hostname.

  6. Take the system out of maintenance mode for the hostname change to take effect.

    Now the original hostname is configured with your new IP address.

Dashboard Issue Failure to Display Meetings That Have Started

In this release of Cisco WebEx Meetings Server, the dashboard can fail to display certain meetings as having started. This issue occurs in the following scenario:

A meeting is scheduled with the Allow participants to join teleconference before host setting enabled. A participant joins the meeting by phone but does not join the web portion. The dashboard should indicate that this meeting has started and has one participant but it does not. This issue can cause users to schedule multiple meetings resulting in performance issues.

Audio Configuration

On your audio configuration settings, G.711 provides better voice quality than G.729. See "About Configuring Your Audio Settings" in the Cisco WebEx Meetings Server Administration Guide for more information.

IP Communicator 7.0.x Endpoints

IP Communicator 7.0.x endpoints joining CWMS meetings can introduce audio quality issues (echo and other noises) to a conference if either of the following conditions occur:

  • IP Communicator is not muted.

  • A participant using IP Communicator becomes the active speaker.

To prevent this issue, fine tune the IP Communicator environment (for example, the headset, microphone, and speaker) or use a different traditional phone.

Meetings that are started with iOS devices cannot be recorded.

Dial-in and Dial-Out Connections to an In-Progress Meeting

When a meeting fails over from one data center to another, the dial-in and dial-out connections to that meeting do not automatically reconnect. To reestablish the connections, participants hang up and manually dial back in.

This problem may occur when:

  • The installed system is a large MDC.

  • The meeting is started while one of the data centers is in Maintenance Mode or is powered down.

  • When, after Maintenance Mode is turned off or the data center is powered on, another data center is powered off or placed into Maintenance Mode.
