Abstract:
In response to a request for a conference call among specified invitees, a conference-call system provides web pages that elicit from respective invitees the telephone numbers at which they can be reached, and it causes messages that contain those web pages' URIs to be sent to those invitees. If a presence network indicates that an invitee's messages will be received on a telephone, the conference system instead sends to that phone a message specifying a telephone number to call and a PIN to be used for that purpose.
