The outbound proxy is the SIP proxy that will relay your calls. The behavior of a SIP proxy is similar to the behavior of an HTTP proxy, i.e. some entity that issues the requests on your behalf and proxies the streams.
Kanpoko proxy-a deiak transmitituko dituen SIP proxy-a da. SIP proxy-aren eta HTTP proxy-aren portaerak antzekoak dira; hau da, zure izenean eskaerak egiten dituen entitate bat, korronteak kudeatzen dituena.
