Your best path here would be to look on WebEx forums and/or contact WebEx Support to see what they offer here. I believe WebEx offer some visualizations for WebEx sessions etc., so if it is not possible to connect directly, you may be able to look into what they offer from their side as well. Potentially, if you can get those visualizations, you may be able to export from there etc. as well.

I now work a compressed schedule, Tuesday, Wednesday and Thursday, so those will be the days I will reply to any follow-up posts.
