Request line and "To" is different, the system will use the number of "To" to dial out.

All Call through OutBound Proxy：An outbound proxy server handles SIP call signaling
as a standard SIP proxy server would. Furthermore, it receives and transmits phone
conversation traffic (media) in between two talking gateways. This option tells the
gateway to send and receive all SIP packets to the destined outbound proxy server

protected network without additional settings or techniques. Please make sure your
