A method for conferencing enterprise and non-enterprise callers, the method comprising: receiving a first call initiated by an enterprise caller at an enterprise; communicating with an enterprise media server to initiate a tributary conference on the enterprise media server; joining the enterprise caller to the tributary conference such that the enterprise caller is in data communication with the tributary conference; receiving a second call initiated by a non-enterprise caller via a public switched telephone network at a gateway of a data center; converting the second call into an internet protocol call at the data centre; interfacing the non-enterprise caller with a data center media server of the data center; creating a home conference on the data center media server; joining the second call to the home conference on the data center media server; interfacing the home conference on the data center media server to the tributary conference on the enterprise media server to form a linked conference between the enterprise caller and the non-enterprise caller; wherein interfacing the non-enterprise caller with the data center media server comprises: routing the second call from the gateway to an application server of the data center; routing the second call from the application server to the data center media server; and establishing data communication between the gateway and the data center media server.
