Telecommunications data conferencing platform having secure firewall wherein access is restricted to messages originating from server but conference data pass freely
First Claim
1. A data conferencing platform for providing a data conference between participants, said data conferencing platform having first and second zones, said data conferencing platform comprising:
- a reservation system located in the first zone;
a data server located in the second zone and arranged to be connected to a communications network; and
an interface between the first and second zones, the reservation system being connected through the interface to the data server;
the reservation system being arranged to make conference reservations;
the data server being arranged to receive details of a data conference from the reservation system and to pass conference data between communications terminals used by participants to a data conference;
the interface between the first and second zone being arranged to restrict the passage of messages from the second zone to the first zone to messages which originate directly in the second zone but allow the passage of conference data;
a master data server located in the first zone and connected to the reservation system and the interface between the first and second zones, the data server in the second zone being a slave data server, the master data server being arranged to receive details of a conference from the reservation system and to pass the details to the slave data server; and
at least one other data server in the second zone, each data server in the second zone being a slave data server, the master data server being further arranged to pass conferencing data between the at least two slave data servers.

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.
