Hi Maqsood

following link states the bandwidth requirement for Cisco Jabber Video.

https://supportforums.cisco.com/docs/DOC-23366

HD-quality (1280x720) video resolution requires approximately 1.3Mbps.
VGA-quality (640x480) video resolution requires approximately 450Kbps

My questions are

does this also apply to Cisco Jabber for Telepresence?
currently only Cisco Jabber for Windows support video call, right?
HD quality video requires about 1.3Mbps, what is the point of assign bandwidth more than 1.3Mbps? resolution still the same, but better quality?
Does Jabber support auto-down-speed during video or audio call? for example, during call setup, both calling and called parties agree the video call should use 1280x720 resolution, bandwidth at about 1.3Mbps. A couple mins later, due to network congestion, there is no enough bandwidth, could the Jabber or CUCM detect the current network situation, automatically downspeed the video and audio call?

thanks

Hi Maqsood,

Will Cisco include support for JID Escaping XEP-0106 (http://xmpp.org/extensions/xep-0106.html) in the next release of Cisco Jabber for Windows? I would imagine this is a major issue for a lot of users. I believe Cisco has an open defect on this: CSCtz76102. Thanks.

Hi Yuke,

Thank you for your post and questions. Please note that I will only be able to answer questions related to Cisco Jabber for Windows. I have provided my input inline below.

does this also apply to Cisco Jabber for Telepresence?

You can ask the question regarding Jabber for Telepresence on the following link or in the Jabber Clients forum.

http://www.cisco.com/en/US/products/ps11328/index.html

2. currently only Cisco Jabber for Windows support video call, right?

Please post this question in the Jabber Clients forum.

3. HD quality video requires about 1.3Mbps, what is the point of assign bandwidth more than 1.3Mbps? resolution still the same, but better quality?

That is correct. Please review "Audio and video reference" topic in the Jabber for Windows administration guide for more details. It also includes a section "Performance expectations for bandwidth".

http://www.cisco.com/en/US/docs/voice_ip_comm/jabber/Windows/9_0_1/b_jabber_win_icg_chapter_01000.html#reference_F78D895015E94383BCDC71BC27CF2E27

4. Does Jabber support auto-down-speed during video or audio call? for example, during call setup, both calling and called parties agree the video call should use 1280x720 resolution, bandwidth at about 1.3Mbps. A couple mins later, due to network congestion, there is no enough bandwidth, could the Jabber or CUCM detect the current network situation, automatically downspeed the video and audio call?

Jabber uses a combination of bitrate history and video rate adaptation to improve user experience for sending video bitrate.

Bitrate history remembers:

- who user calls (phone number )

- from where (network adapter Gateway chosen for sending media)

- last known sending video bitrate

Note: Bitrate history is saved in bandwidth.properties file under C:\Users\usernameAppData\Roaming\Cisco\Unified Communications\Jabber\CSF\Config

Video rate adaptation starts at low bitrate (128 kbps) and doubles bitrate every 3 seconds (approx) until limited (network/signalled/region) value is achieved.

If you have previously called a user and it has adapted to HD (will take approx 30 seconds), subsequent calls to this user will start at HD. However video call will adapt (high or low resolution) if network conditions change (up or down).

Hope this explanation helps.

Thanks,

Maqsood

Hi Bill,

Jabber for Windows team has resolved JID escaping defect CSCtz76102. This fix will be available in the first maintenance release of Jabber for Windows. I do not have a release date for this but it is targeted for early to mid June at the moment.

Thanks,

Hi Maqsood

Thanks for the quick reply.

Couple more questions

Does Jabber for Windows support audio sharing via presentation? e.g I am running Jabber, connected with Ex90, then I play a video clip on my notebook, shared via presentation, on Ex90 can hear the audio from video clip?
Is Jabber going to add permanent chat group function? In China, there is a very popular IM software called QQ, it has permanent chat group function, capable of audio and video. People can join groups for specific topic, like "Cisco Network Engineer group", or from within a company, can create "Cisco TAC - UC" group, "Cisco TAC - Data Center" group, peple can post questions, share ideas. I have seen a lot of companies using QQ for business as well. For Pepole in China, if QQ can do the same thing as Jabber, what is the point of getting the Jabber in the compnay network?
Can Jabber for Windows make sip call? I know Jabber for Telepresence can, it use VCS control and VCS Expressway.

thanks

Hi Yuke,

Please see inline.

- Jabber for Windows does not support audio sharing via presentation video. However since for the video presentation sharing you need to be on a call, the audio from a video playing on your desktop can get transmitted to the receiver if you are using pc speakers for audio out. In this case audio will be picked by your mic.

- Persistant group chat feature is on the roadmap for Jabber for Windows.
- Cisco Jabber for Windows is part of Jabber product suite which provides rich collaboration and communication from any workspace including PC, MAC, tablet and smartphones. Depending on the business needs of an organization, Jabber can provide significant increase in productivity and cost savings. Following link contains some helpful information about Jabber solution and case studies.
  https://communities.cisco.com/docs/DOC-29850
Can Jabber for Windows make sip call? I know Jabber for Telepresence can, it use VCS control and VCS Expressway.
- Jabber for Windows always makes SIP calls in softphone mode.
- If user is in deskphone mode:
  - SIP call is made if the deskphone has a SIP based phone firmware
  - SCCP (Skinny Call Control Protocol) call is made if the deskphone has an SCCP based phone firmware

Muhammad Maqsood Mushtaq — Tue, 05 Jun 2012 13:28:07 GMT

Hi Yuke,

Jabber for Windows supports uri based sip calls.

Example 1:

A user can make a call from the run window as below:

Example 2:

Owner of a web page can use links similar to this:

Call reception

Clicking on this link will pop up a Jabber confirmation dialog as in above example (if Jabber is not started it will automatically be started).

Thanks,

Hi Maqsood,

I have a potential client who is very interested in a full scale Cisco solution including WebEx, Jabber presence/IM client, Video and the Business Edition 3000.

They have one very important concern however and I haven't been able to find a way to address it so I'm hoping you can help me.

Their entire organization is mobile and for that reason they use Microsoft Terminal Services for all access to their company applications and files (they have been very happy with this set-up and are not willing to change). Additionally, they don't currently have or want a VPN. From my understanding the Cisco desktop applications their interested in aren't supported in Microsoft Terminal Services but still may work.

Are you aware if these applications would work in their environment?

Also, does Cisco have any plans in the near future to support their applications in Microsoft Terminal Services?

Thanks,

Casey

Muhammad Maqsood Mushtaq — Tue, 05 Jun 2012 16:03:06 GMT

Hi Casey,

Jabber for Windows team did not do any QA work on Microsoft Terminal Services. Therefore I cannot comment if Jabber for Windows (along with other Cisco products) will work on MS Terminal Services and if it works at all what will be the quality of the products. There is no formal support for Jabber for Windows under terminal services. Also there are no committed plans for testing/supporting Jabber for Windows on MS Terminal Services.

Thanks,

Maqsood

Re: Ask the Experts

Muhammad Maqsood Mushtaq — Wed, 06 Jun 2012 17:27:55 GMT

Hi Jacob,

Can you check in your registry if following registry folder and its values exist?

Key = HKEY_CLASSES_ROOT\tel

Value = URL:Cisco Jabber Protocol

Key = HKEY_CLASSES_ROOT\tel\DefaultIcon

Value = C:\Program Files (x86)\Cisco Systems\Cisco Jabber\CiscoJabber.exe

Key = HKEY_CLASSES_ROOT\tel\shell\open\command

Value = "C:\Program Files (x86)\Cisco Systems\Cisco Jabber\CiscoJabber.exe" -URI %1

When Jabber for Windows starts it adds these registry entries if they do not already exist. If the folder or subfolders don't exist then your user may not have enough privilages to allow Jabber to write to this registry location although we did test it for non-admin users. Please provide a problem report if registry entries are missing.

Thanks,

Maqsood

Dear Maqsood Mushtaq

One of our customer is planning to Configure Unified Communication Manager Directory Integration in a Multi- Forest Environment. I had checked that CUCM and Unity Connection support multi forsest directory integration. I would like to know if jabber for windows also support Multi forest directory integration.
