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.

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

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

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

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.

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.

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.

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.

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.

This release introduces support for Cisco Jabber Release 11.8.

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.

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.

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

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.

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.

• The directory exists.

• The files are present.

• The checksum is correct.

• The folder is in CWMS storage.

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

This release supports the following Cisco Network Recording Player versions:

This release supports WebEx Productivity Tools version 2.82.7000.1174 for Windows.

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.

EMC SourceOne

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

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

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.

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.

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

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.
