Abstract

A telecommunications data conferencing platform has a secure zone and a partly secure zone connected by a secure firewall. The secure zone contains a master data server, a billing system a reservation system and an audio bridge connected to the firewall. The partly secure zone contains a pair of slave data servers. The first slave data server can be connected through a public firewall to the public Internet. The first slave data server can receive incoming calls from the public switched telecommunications network via a bank of modems. The secure firewall restricts the passage of messages from the partly secure zone to the secure zone to messages which originate directly in the partly secure zone but allows the passage of conference data. Thus, unauthorised parties are unable to gain access to the reservation system or the master data server. In order to establish a conference, the reservation system creates a conference on the master data server. The master data server then invites the slave data server to join the conference. The slave data servers then permit participants to join the conference.
