Abstract
A method and system are provided that enhance human/machine communication so as to more closely approximate natural human/human communication by more effectively establishing communications links for human-interactive media. Specifically, the speed and quality of the connection are improved by the method and system, resulting in a more natural user experience. The method includes receiving a Session Initiation Protocol (SIP) call request from an Endpoint (EP). The method determines an external address based on an internal address of the EP uniquely mapped to the external address and pre-distributed to SIP internal routers. The method includes modifying the SIP call request to replace the EP internal address with the EP external address. The method includes forwarding the EP external address to the EP. The method includes establishing a communication link for human-interactive media between the EP and the call provider, the EP using the EP external address, and the communication link not including the SIP Internal Router.
