INTRODUCTION:There is 4 types:
1. Webex share – Available when BFCP or IM only is not available2. BFCP Share – Available when on a call3. IM Only Share – Available when chatting over IM.4. Escalate to a meeting and share
Colin Flaherty (coflaher) | Cisco
WEBEX SHAREEXPLAINATION:
This type of share is the default share type if BFCP and IM Only share is not available. When the other integrations are disabled or if you are sharing with a user that doesn’t have those capabilities, then it will default to this share. It can also be started by the first two options that I outlined below. The user experience is similar to the Webex connect client
HOW TO ESCALATE USING JABBER: OPTION 1 (WHEN OTHERS TYPES ARE ENABLED)

HOW TO ESCALATE USING JABBER: OPTION 2 (WHEN OTHERS TYPES ARE ENABLED)

HOW TO ESCALATE USING JABBER: OPTION 3 (WHEN OTHERS TYPES ARE DISABLE/OTHER USERS DOESN’T HAVE THE CAPABILITY)
POP-UP SHOWN TO OTHER USER:

LOADING SCREENSHARE:
SCREENSHARING TOOL:
SCREEN THAT OTHER USER SEES: (NO RED-LINE AROUND IT)

IM ONLY SHARE
EXPLAINATION:
IM Only share is point to point. To initiate an IM only share, you need to open a chat window with someone and select “Share screen”. The person sharing will see a red line around their screen. See below. The port range is huge so so some customer firewalls will have it blocked.

BFCP SHARE
EXPLAINATION:
BFCP goes through CUCM. Has a similar user experience to IM only share. To initate a BFCP share, you need to be a call and then select “Share screen”. See below.
HOW TO ESCALATE USING JABBER:

SCREEN THAT OTHER USER SEES: (RED BOX AROUND IT)
NO POP-UP SHOWN TO OTHER USER:
If you escalate in a call, there is no pop-up and it goes straight to a desktop share.

HOW TO DISABLE: (VIA JABBER-CONFIG)

STANDARD WEBEX MEETINGEXPLAINATION:
This is a standard webex meeting. You can escalate to a meeting and then share your screen like a normal meeting.

HOW SCREENSHARE WORKS ACROSS THE CLIENTS (CLOUD)
No. 2 is wrong if MAC user is using a BFCP supported version. In that case a MAC and Windows user will do BFCP.

DEBUGGING
DEBUGGING NETWORK ISSUES (P2P DESKTOP SHARE)
Unfortunately wireshark does not show the RDP packets so it can’t be used to see if network packets are being sent between the two machines.
However you can use a MS tool called: Microsoft Message Analyzer,
http://www.microsoft.com/en-us/download/details.aspx?id=44226
To use it you simple go to:
Start local trace.
The trace you see will be something like below:
The address’s are in ipv6 so you’ll need to know the host and remote address in ipv6 format.
TEST WITH MICROSOFT SCREENSHARE TOOL
Download the following tool:
DOWNLOAD:
https://cisco.box.com/s/ref6mt8om05yymwushruow25a0wj5rh9
STEPS:
Step 1: Copy the files in the download to both machines.
Step 2: On machine one, unzip the file and navigate to this folder: WinPresenterFinal\WinPresenter\WinSharer\bin\Debug
Step 3: Click on WinSharer.exe.
Step 4: Select “Start presentation”. This creates an xml called inv.xml.
Step 5: On machine two, unzip the file and navigate to this folder: WinPresenterFinal\WinPresenter\WinViewer\bin\Debug
Step 6: Copy inv.xml into this folder.
Step 7: Click on WinViewer.exe.
Step 8: Select connect

If the sharing doesn’t work, then this proves it’s not a Jabber issue with P2P desktop share and is likely a network issue.
CONFLICTING SOFTWARE
Calabrio Monitoring and Recording Desktop Recording Service has a known conflict with Jabber and P2P desktop sharing
To see if this service is running, do the following.
Go to Run Type in “services.msc” Scroll down to “Monitoring and Recording Desktop Recording Service” to see if its running.
The following is a response from the Calabrio support team:
“This OS API that both QM and Jabber use is the Microsoft Windows Desktop Sharing API. This API has the limitation where only one application can use it at a time. Earlier comments in the case notes indicate that the customer wanted to share screens using the Jabber application. In that case, they can disable Live Screen Monitoring in QM Administrator under "Interface Settings", just uncheck the box next to "Enabled". You will need to restart the desktop recording services in order for the Live Screen Monitoring functionality to be turned off so that Jabber can be used to share screens.”
FIPS
Jabber P2P desktop share does not support FIPS mode.
