Good day! My name is Dmitry! Have Cisco TelePresence SX20 + VCS 8.2 server and Skype for business 2015. Is it possible to set up a conference call on SFB and to call on all subscribers of this conference ?. At the moment we can only call on one customer and SFB. We have the current version of the software SX20 TCNC22.214.171.1245090 - is it possible it obnoviti 7, and will it help to improve the situation ? Thank you!
