Vox SIP Redirect is positioned between SBCs and rate management servers, receiving route updates in real time, but only delivering the updates and routes to the SBC/softswitches on-demand. SBCs/softswitches are no longer required to perform the complex routing decisions, reducing load so that CPS and concurrent call handling capacity are increased.

Whenever a call needs to be routed, the SBC directly forwards the request to Vox SIP Redirect without performing any routing logic. The SIP redirect server then performs the required routing logic as per the rates update received from rate management server and sends the response to the SBC the appropriate call route through which the call should be terminated.
