A global multimedia server, local multimedia server and multimedia client create a universal communication system allowing any consumer to engage a plethora of media content to any end user. The global media server may be located through a publicly accessible IP address using a FQDN (fully qualified domain name) based on DNS. The delivery of multimedia calls or messages may also be achieved by using an E.164 number as universal resource identifier. PBX features allow for the manipulation of multimedia content and the use of mixed and multiple media during a communication or the creation of spontaneous or scheduled conferences that are both collaborative and interactive.
