following link states the bandwidth requirement for Cisco Jabber Video.
My questions are
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.
2. currently only Cisco Jabber for Windows support video call, right?
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?
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?
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 for the quick reply.
Couple more questions
Please see inline.
Jabber for Windows supports uri based sip calls.
A user can make a call from the run window as below:
Owner of a web page can use links similar to this:
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).
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.
yep its a permission problem
my pc with windows 7 pro 32 bit
the key was missing
exited jabber and ran by "run as administrator"
and the key got added and dial works from run
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.
@="URL:Cisco Jabber Protocol"
@="C:\\Program Files (x86)\\Cisco Systems\\Cisco Jabber\\CiscoJabber.exe"
@="\"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.
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.
