Desktop Sharing during a VideoCall is not working

[Thomas Leitner]

Hey Community,

I need your help ...

I've a problem with jabber for windows ... (with the configuration on the CUCM ...)

if I start a chat ... the desktop-share functionality is available ... but within a videocall the icon is grayed out :(

... the environment is a newly installed CUCM system version 11 ...

the clients are all onprime ... and are all jabber for windows version 11.1.1 ...

do you have a hint for me? :)

thanks in advance!

best regards, thomas

If it works on chat, that should mean BFCP is enabled, doesn't hurt to check.

You might also want to review that CAC is not preventing this.

Hey :)

thanks for your answers ... I've checked the sip profile ... and the tick next to allow bfcp is enabled / set ...

... what was your other mentioned idea to check?

thanks again :)

br, Thomas

Hey,

sorry the question again ...

The problem has a changed a little bit ... the screensharing is now possible, but the button "request control" is grayed out.

is there any known limitation regarding this feature?

thanks in advance :)

br, Thomas

Hi,

Is this a point to point call between two Jabber clients or is it multi-party hosted on a bridge?

I did find a parameter in the 10.6 Deployment guide, in the jabber config file generator could not find in the 11.x guide :

http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/jabber/10_6/CJAB_BK_C56DE1AB_00_cisco-jabber-106-deployment-and-installation-guide/CJAB_BK_C56DE1AB_00_cisco-jabber-106-deployment-and_chapter_01010.html

PreferP2PDesktopShare
Specifies that person to person screen sharing is preferred over video sharing.
true — Person to person screen sharing is preferred.
false (default) — Video sharing is preferred.

I cannot locate any clear definition of screen sharing vs video sharing but kind of eludes to a difference. If you cannot control in a jabber to jabber video call (on two laptops for instance) perhaps set this parameter to true and do a test. You would also need to test what happens when dialed into a room system or multparty conference. I would actually like to test myself but not able to at this point.

Let me know how this turns out.

Hey :)

thanks for your answer ...

after deploying the jabber-config file ... the first two calls didn't work, after a few minutes it works now :)

THANKS again for your help!

I have a linked problem here, similar but not the same.

Jabber multiparty desktop share works from a group chat

From a multiparty video call it does NOT work.

We are using conductor and vTPS for our multiparty video conferencing.

I noticed the following from the install guide:

Video desktop sharing using BFCP is not supported during Cisco Jabber multi-party conference calls unless Cisco TelePresence MCU is deployed.

As I understand it, vTPS is a replacedment for an MCU. Does anyone have any further info?

If the Sharing button is disabled on the Call Window, this is definitly BFCP desktop sharing.

Bascailly, there are two types of Desktop sharing in Jabber

1) P2P (No phone call requried, Desktop share buttong is available on the chat window)

2) BFCP (CSF Call required, Desktop share button is available on Call Window after the call is establisehd). BFCP has limitation, such as it must be a softphone Call using CSF device and BFCP must be enabled on call Manager etc.

BFCP desktop sharing is similar to Softphone call where the BFCP parameters are negotiated durign SIP Invite message within SDP of the SIP

Here is details about BFCP sharing

Note: Mobile clients only support BFCP receiving

Hi Thomas

If the icon is still greyed out during a call, you need to check the other considerations for video desktop sharing which are given here:
