Traditional audio conferencing services require the Kingdom Hall to have a PSTN phone line in order to initiate an audio conference. When a Kingdom Hall moves to the NBN, they are no longer provided with a PSTN phone line which makes a traditional audio conference solution incompatible. (There are a few exceptions to this. Please see this page for more details)

The Vattendance IP solution comes with new hardware that bypasses this issue. It runs Voice over IP (VoIP) end to end meaning no traditional phone line is required at the Kingdom Hall.

Your callers can still dial in from a traditional phone line however.
