Personally, I don’t read that line as that feature. IM-only screen share I
believe would imply the RDP-based live presenting instead of the in-call BFCP
stream. Screen capture should theoretically be identical to the file transfer
feature, so the fact that it doesn’t work is very strange. Can you copy-paste
images from windows snipping tool into the text box in MRA? That should
theoretically be the same kind of data since it’s an in-stream picture with
text.

Subject: Re: [cisco-voip] Jabber Screen share over MRA
Nice find! Thank you! An odd thing to take a vendor to task over, but when
screen captures are important ... I guess they are important.

The native screen capture in the Jabber client does not work and is not
supported over MRA (internal or WebEx Messenger IM Jabber works fine).
I believe it is actually covered by the same Expressway caveat that states
native P2P file sharing won't work over MRA. By using MFT (Managed File
Transfer), both should be allowed.
My question to the group is, does anyone know where the Screen Capture over MRA
limitation is specifically documented? It uses the same P2P technology that the
file share does, so it makes sense that it doesn't work over a proxy like
Expressway, but I'm in need of specific documentation.
I have opened a case with PDI to confirm my suspicion about the feature, so I
am confident Screen Capture doesn't work over MRA (and why it doesn't work over
MRA). I also found this bugId for the lacking statement in the Expressway docs:
https://bst.cloudapps.cisco.com/bugsearch/bug/CSCuu22458/?referring_site=bugquickviewredir
So my guess is this is an oversight by the technical writers and/or assumptive
on Cisco's part that the reader would just "assume" the screen capture feature
is really just a P2P file transfer under the hood, even though there is GUI
magic with a screen capture making the end user workflow a little different
than a file transfer and leads many to believe otherwise.
Has anyone ever seen anything to this regard, documented on official cisco docs?
Thanks,
Ryan
