resubmitting with additional details -
When a user makes call to me with the WebEx client, I can choose to answer the call (screenshot 1). The audio portion of the call is routed through speakers or headsets connected to the device where the client is installed, usually a computer. When the caller shares their screen, I see it on my WebEx client, and we discuss the shared content.
I would like the option to transfer the audio portion of the call to a PSTN number so that I can communicate with the caller via my phone (perhaps mobile, perhaps a desk phone) but when the caller shares their screen it is still displayed on my WebEx client where I answered the call.
If I were to answer the call with my mobile webex client, any shared content would be displayed on that, much smaller, screen.
this function would be similar to call me feature that is available for meetings (screenshot 2), but I think it should be available for direct 1:1 calls as well.
