Organising an audio conference with Vidyo is as easy as organising a Vidyo meeting:
1/ Create an Indico event (http:indico.cern.ch)
2/ Add a Vidyo virtual room to the Indico event
3/ Invite participants by sending them the Indico URL
Note: Like any other Vidyo meetings, these meetings can be joined not only by phone, but also via the standard desktop or mobile clients and by conference room systems (H.323 standard).
