Hi, yes that was enabled in mid of this year, see here https://help.webex.com/en-US/article/rdmb0/What's-new-in-Webex-Calling more details. AFAIK it's not allowed on Cisco PSTN yet, so only CCPP/LGW and in US/CAN.  

Pls check those 2 urls if you made all steps correctly: https://help.webex.com/en-US/article/nojp8ej/Configure-Voice-Portals-for-Cisco-Webex-Calling-in-Control-Hub https://callinghelp.webex.com/voice-portal-feature-video-for-administrators/  

Hi, Yep, this is correct even if definitely maybe misleading. Instead you will see the status of headsets that would be registered to DECT network. BR/

Hi, I don't have a library but my strong recommendation would be to use as much as you can Slido for any type of the workshops that you are running. It definitely helps with audience engagements, collecting feedback, issues, problems etc.
