It is possible to record any phone call to MediaSense. It can be used to record a Webex, but it would appear just like a phone call with two parties. One side is the receiving phone and the other is the whole meeting.
The way to do this is to trigger the Webex call to MediaSense. You can directly add in MediaSense as a participating phone, has to be done manually, or trigger from one of the physical devices or use a CUBE.
Why are you looking at MediaSense and not the already available WebEx recordings?
You can unicast me at anilve@cisco.com for more discussions about the business case.
Thanks,
