Managing Conferences

Aculab Cloud supports unreserved small conferences of up to 40 participants, and reserved large conferences with up to 350 participants (see Conferencing Capabilities). This document describes the web services that can be used to reserve large conferences and to manage participants of conferences in progress of all sizes.

 Please note that the large conference feature is not enabled by default on Aculab Cloud accounts. Please contact us if you would like to use this feature.
 This is a low level API. For information on higher level APIs see the Web Services Language Wrappers

Note on Conference States

During its lifetime, a conference passes through several states, and some of the web services can only act on conferences whilst they are in a specific state. To discover the current state of a conference, use Conference List.

StateDescription
RESERVEDa conference that has been reserved using Conference Reservation Create, but has not yet started.
HOLDINGa conference that is about to start. Participants are holding waiting for the conference to become active.
ACTIVEa conference that currently contains two or more participants, including the leader.
COMPLETEDa reserved conference that has finished.

  • Conference Reservation Create

    This makes a conference reservation on the Aculab Cloud for a number of participants, at a specified time and for a specified duration. Attempts to connect a participant into the conference between the booking being made and the conference start time will be rejected with a cause of BUSY unless the optional divert parameter is supplied. In that case the conference connect will be diverted to the specified inbound service which can play a "call back later" message.

    Password : API Access key

    Request:

    Url:https://ws.aculabcloud.net/conference_reservation_create
    Methods:GET, POST

    ParameterValueDescription
    conference_namestringa name for the conference, consisting of fewer than 48 alphabetic or numeric characters. This will be referenced by applications connecting to the conference.
    max_participantsintegerthe maximum expected number of participants. Must be between 40 and 350.
    start_timestringthe required start time in UTC, in the format YYYY-MM-DD_hh:mm:ss or YYYY-MM-DD-hh-mm. The time is rounded down to whole minutes. Must be at least 5 minutes in the future, but no more than 24 hours.
    durationintegerthe required duration in minutes. Must be between 15 and 480.

    A JSON object containing the following properties:

    ParameterValueDescription

Only reserved conferences in the RESERVED, ACTIVE or HOLDING states can be modified, and then only by extending the conference duration, providing that the conference is not already due to finish in the next five minutes. The overall duration cannot be extended beyond a total 480 minutes. (See Note on Conference States for details on conference states.)
