Esna WeLink Conferencing allows users to have a conference call or a voice meeting over a pre-existing telephone system. Once all the server side configurations have been completed by the system administrator, the person who has the Moderator access code will have the ability to control the different rooms in the conference system. The Moderator can be seen as the conference room’s chairperson who has the ability to invite other participants to the conference. The Moderator may also modify different types of settings that are related to the conference rooms such as the recording functions or the background music.
