External H.323 or SIP Client
In EVO, it is possible to call any H323 or SIP client directly from Koala. You have two options to invite remote participant to join the meeting: (1) to make a call from inside the meeting to invite him/her to join this particular meeting or (2) to make the call without joining a meeting. In this later case, the system will automatically create a Private Meeting and put you in.
In the Koala menu click on the
icon and then choose “Call H.323/SIP client” menu item.You can manage such calls also from the Address Book (
button of the Call widget).
