Hi Marcelo,Please find the

Hi Marcelo,

Please find the answers to your questions below:

1) The real-time collaboration tools and features in CWMS are mostly same as that in Cloud WebEx. However, CWMS has features like behind-the-firewall design, advanced administration and high-availability.

2) There have been many new and changed features with every release of CWMS (1.0, 1.5, 2.0 and 2.5). You can find the details of the same documented in the release notes here:

http://www.cisco.com/c/en/us/support/conferencing/webex-meetings-server/products-release-notes-list.html

3) In order to get the migration licenses for CWMS from MP, you will need to contact the Cisco Licensing team. They will be able to validate the contract and provide migration licenses.

4) Document to configure CUCM for CWMS: http://www.cisco.com/c/en/us/td/docs/collaboration/CWMS/b_planningGuide/b_planningGuide_chapter_0101.html

Document to configure audio on CWMS: http://www.cisco.com/c/en/us/td/docs/collaboration/CWMS/2_0/Administration_Guide/Administration_Guide_chapter_01111.html#task_4A38FDE60C9C4A56946C0B288B469900

5) There are no configuration changes documented to support CMR.

6) We work on a wide range of issues with CMWS like installation/configuration/upgrade issues, database replication issues, audio quality and so on. Its hard to specifically point the #1 case.

Please let me know if any further questions.

Thanks,

Jyothi

ESXi 5.1
No snapshots

 

Can you please suggest me some key step to initiate process  and highlight some important point to remember as upgrade document is huge...

1. Backup your existing system (1.5 MR3) using your NFS server

2. Deploy new VM using upgrade OVA

3. Copy data from existing system to Admin VM of new system

4. Deploy the rest of the VMs for upgraded system

5. Test the upgraded system

Prerequisites:

1. OVA for the upgrade version

2. Sufficient disk space on UCS for the new Admin, Media and IRP VM of the upgraded system

I am trying to deply CWMS but in the initial wizard I got the following error:

 

Please try again as the server encountered an unexpected error. If the problem persists, contact Cisco TAC and provide the following information:<br/>(Internal Server Error (request id: 2041, internal data: {"readyState":0,"responseText":"","status":0,"statusText":"error"})).

Hi,

 

Could you please provide us a screenshot of the error message? I believe the error message is seen while using the deployment URL. Correct me if I am wrong. Also, could you please provide me the webex site URL and the admin URL that you are adding? Please make sure that the DNS resolution for the webex site URL and the Webex administration URL is configured.

Hi Deval, Key points to

Hi Deval,

 

Key points to remember during the upgrade process,

 

  • Your current version has 1.5.1.323.A, hence, please make sure that you obtain the encrypted version of 2.5 OVA from the PUT tool. [Should have AE in the version name]
  • Make we have enough disk space in the ESXi hosts [990GB].
  • Remove all the VM snapshots, if they exists.
  • Make NTP on ESXi is configured and is in sync.

 

With regards to configuring, there is no nothing that needs to be done. The system will be able to operate with the configuration that was done in 1.5 version. 

 

The license in 1.5 is changed in 2.5. Hence, we should order the license while ordering the OVA via the PUT tool. Once the PUT ordered is processed, you will be provided with a new PAK using which you can obtain the license.

Beginner

Hi Team, Thanks for your

Hi Team,

 

Thanks for your suggestion, I am in process of making upgrade plan will share details once completed.

 

I have two queried related to WebEx welcome IVR.

 

My Current setup:

1.5.1.323.A
250, with IRP no HA

UCS-C220-M3S vCenter + Media + Admin
UCS-C220-M3S IRP
ESXi 5.1
No snapshots

 

1. Can we customize the IVR to company specific

e.g. Welcome to XYZ company WebEx services...

If Yes, can you please share the process,

If not, can I have some reference document for same.

 

 

2.  I am facing issue with call-in IVR message.

My dial-in and out calls from WebEx are working very fine

However there is issue observed in some dial-in calls,

I can see calls are connecting, however after that its total blank, welcome IVR of WebEx is not played.

Users get confused on what to do next. This happens at random time random user...

This has started happening since 15 days.

 

I have checked WebEx  server health and server connection everything is fine.

I have also restarted whole WebeEx cluster, still issue persist.

 

Please let me know your suggestions.

Hi Deval,

 

Please find the answers to your questions below:

 

1. Customization of audio prompts is not supported on any version of CWMS yet. We have a feature request with the engineering team for the same but if has not been added to CWMS yet.

CSCug29833 : Prompt customization

2. This seems an issue with audio clipping or audio quality on your CWMS calls. Please verify the following:

a. Please check if you are on supported hardware and the conditions for no co-resident VMs are met:

http://www.cisco.com/c/en/us/td/docs/collaboration/CWMS/2_0/Planning_Guide/Planning_Guide_chapter_01011.html#reference_249B138B71324D19B09141D3849EC058

b. There must be no snapshots on any of the virtual machines for the system. If you have captured any snapshots before an upgrade, ensure that you delete them within 24 hours as they cause degradation of system performance and are known to cause audio quality issues.

c. Please check your network bandwidth against these requirements:

http://www.cisco.com/c/en/us/td/docs/collaboration/CWMS/1_5/Planning_Guide/Planning_Guide_chapter_01.html#reference_267DB686BB224EB7A49DE4C783C912E6

Please cross-check the above mentioned details and if you still face the problem, feel free to open a TAC case to troubleshoot the issue further. We will be able to get detailed logs and sniffers to debug and find the cause of the issue.

Hi Amit Singh, Haran S M and

Hi Amit Singh, Haran S M and Jyothi V,

 congratulations for the excellent topic.

1) Is there any differences in features between CWMS (on-premises) and Cisco Webex Meeting Center (cloud)?

2) What is the main differences between CWMS 2.x and CWMS 1.x?

3) With the end of MeetingPlace, CWMS became a migration path for the customer ... is there any document that describes this migration installation? What is your recommendation?

4) About CWMS and CUCM integration ... any good document about the installation & configuration?

5) With the add of CMR in the Cisco Webex Meeting Center environment, what kind of installation/configuration changes we need to do to support this? Any recommendation?

6) What's TAC #1 case about CWMS that we should take extra care?

 

Thanks in advanced.

H Marcelo, To answer 3rd

H Marcelo,

 

To answer 3rd query, while moving from MeetingPlace to CWMS, it can be considered as a new install, since your existing meeting / information from meetingplace cannot be moved to CWMS. However, the meetingplace licenses can be migrated to CWMS license.

Hi Team,First of all thanks

Hi Team,

First of all thanks for doing this knowledge sharing event.

I have a query about the MDC system. The documentation says users access the system using a single link and it appears as one system to the users.

Lets say users are based on two Sites A (geographically close to DC1) and Site B(geographically close to DC2). We want to direct Users on Site A to DC1 and users on SiteB to DC2.

How can we achieve this?

This is just for two sites, how can we set preference for users on multiple sites?

Hi Terry,In a MDC system, the

Hi Terry,

In a MDC system, the users are not specifically configured to a DC. The CUCM is configured with preference to the SIP trunks to the local DC. Please see the details below:

http://www.cisco.com/c/en/us/td/docs/collaboration/CWMS/2_5/Planning_Guide/Planning_Guide/Planning_Guide_chapter_0111.html#concept_8C0B2DAC587B4E7A9F8A10798D668C43

"Each CUCM cluster can have INVITE trunks to all the data centers. The call-in route pattern gives priority to the INVITE trunk associated with the local data center and uses the INVITE trunk to the remote data center only upon failure."

Thanks,

Jyothi
