<p>A method for outsourcing Internet call processing functions from a session initiation protocol (SIP)-compliant proxy to a third-party call processing entity comprises the steps of executing a call processing language script in the SIP-compliant proxy, detecting an external-switch, transferring call processing to the third-party identified in an external switch parameter, detecting an external-result, decoding the external-result and completing the call processing using information in the external-result. Similarly, a system for outsourcing Internet call processing functions to a third-party call processing entity from a session initiation protocol (SIP)-compliant proxy is described, which comprise a device for executing a call processing language script in the SIP-compliant proxy using an interpreter, communication between the call processing language script and the interpreter and communication between the interpreter and the third-party call processing entity.</p> |
