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 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 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.

- 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

hi Maqsood

thanks.

Maybe I should ask can Jabber for Windows make url based sip call?

Yuke

Muhammad Maqsood Mushtaq · ‎06-05-2012

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,

Maqsood

wuyuke1982 · ‎06-05-2012

Hi Maqsood

I see. but how about calling sip url? e.g. johndoe@xyz.com?

what u just point out is calling internal numbers.

thanks

Yuke

Muhammad Maqsood Mushtaq · ‎06-05-2012

Hi Yuke,

Jabber for Windows does not support this format of calls today. It is a long term roadmap item.

Thanks,

Maqsood

Hi Maqsood

Thanks for the info.

hi

i have jabber installed and working

but i tried the tel:XXXX and i get error "there is no program associated...."

Muhammad Maqsood Mushtaq · ‎06-06-2012

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

Jacob Berger · ‎06-06-2012

yep its a permission problem

my pc with windows 7 pro 32 bit

UAC enabled

the key was missing

exited jabber and ran by "run as administrator"

and the key got added and dial works from run

pbordeleau · ‎11-29-2012

Hi Maqsood,

I was having the exact same problem until I read this thread.

This has helped me somewhat. Running as administrator did indeed create the missing keys.

Now, when I click on a tel link, Google Chrome opens!

The keys seem perfect, I don't understand why Chrome is opening tel protocols.

[HKEY_CLASSES_ROOT\tel]

@="URL:Cisco Jabber Protocol"

"URL Protocol"=""

[HKEY_CLASSES_ROOT\tel\DefaultIcon]

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

[HKEY_CLASSES_ROOT\tel\shell]

[HKEY_CLASSES_ROOT\tel\shell\open]

[HKEY_CLASSES_ROOT\tel\shell\open\command]

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

When I uninstall Chrome, Cisco Jabber (9.1.0 Build 12296) opens all tel links correctly.

When I reinstall Chrome, Chrome now takes over opening the tel links.

When I go into "Set Default Programs", select Google Chrome, select "Choose defaults for this program", I can see that the current default for the TEL protocol is associate with

Google Chrome. There's a checkmark next to TEL that I can't remove. (see attached image).

Currently using Windows 8 Pro 64-bit.

Thank you for your help, uninstalling Chrome permanently is not a possibility.

Hi Patrick,

Can you reproduce this on Windoes 7 or XP? Please note that Jabber for Windows is not officially supported on Windows 8 yet. It is on the backlog for CY2013.

Thanks,

Maqsood
