Legacy public conference calls A Notify conference call can be public. Note: This content applies only to the Legacy Notify application, available prior to the Geneva release. For information about the Notify application available starting with Geneva, see Notify. The Private field on the conference call record indicates if a call is private (selected) or public (not selected). By default, all calls created automatically, such as those created through Incident Alert Management, are public. You can create private calls using the Notify API initiateConferenceCall method. When created, public conference calls generate an associated Code which is sent via SMS to all invited participants. These participants can distribute the code to allow other users to join the public call. An administrator can control the format of the code using the property glide.notifynow.conference_call.code.pattern. Anyone with the code can connect to a public conference call using one of these methods: By calling the Twillio phone number and entering the code for that conference call. By sending the code in an SMS message to the Twillio phone number. Participants that join a public call this way are considered ad-hoc participants, indicated on the participant record.
