[jitsi-users] troubleshooting webex connect


#1

Hello,

I would like to use Jitsi as a rich-media (read: audio/video) client
to Cisco's WebEx Connect chat platform, which is based on XMPP. I can
successfully authenticate to it and all the contacts appear with the
"begin chat" icon, but none that I have identified so far offer audio
nor video initiation options.

I am unclear whether this is a misconfiguration on my part, or if
WebEx Connect is using a proprietary system which would prohibit me
from doing that (even under successful configuration conditions).

How can I diagnose, or best provide information to have someone help
me, whether it is possible to use Jitsi as a full-featured WebEx
Connect client?

  Thanks kindly,

p.s. I was using the latest win64 build as of 25 May on Win7/Enterprise/x64.

I am not familiar with the protocol used by WebEx but I would assume
this to be the most likely reason indeed. Jitsi shows the audio and
video call buttons if it detects support for standard Jingle from the
corresponding contact.

If we are not showing the buttons for your WebEx contacts then they are
most probably not advertising support for Jingle.

How can I diagnose, or best provide information to have someone help

The logs would probably help confirm the statement above, so feel free
to send them over if you'd like us to have a look.

Cheers,
Emil

I also had a thought that perhaps the pcap of a successful audio/video
chat using the actual WebEx Connect client may be helpful. If that's
true, I have two further questions:

1. What should the pcap filter contain in order to avoid logging
extraneous packets?

2. It is also likely that Connect uses SSL, which would make the pcaps
not very useful. Is there a standard mechanism for "protocol sniffing"
in those cases?

I discovered that the Connect client will honor an HTTP proxy, so I
plan on trying it with a sniffing HTTPS aware proxy and see what that
yields, but I am still interested in hearing about how one solves the
SSL-pcap problem.

  Thanks for your help,

Hey Matthew,

The logs that I asked for already contain pcaps generated by Jitsi.

The only disco#info query that I saw in yours was sent toward someone
using adium and they obviously don't have audio/video support. Could you
please send me the logs of a session where you have already gone through
numerous contacts of your list ... or at least the ones you were
interested in?

Thanks,
Emil
