Outbound Proxy
All Call through OutBound Proxy：An outbound proxy server handles SIP call signaling as a
standard SIP proxy server would. Further, it receives and transmits phone conversation traffic (media)
between two communication parties. This option tells the gateway to send and receive all SIP
packets to the destined outbound proxy server rather than the remote gateway. This helps VoIP calls
to pass through any NAT protected network without additional settings or techniques. Please make
sure your VoIP service provider supports outbound proxy services before you enable it.
E.164
International Call Prefix Digit: Enter the International call prefix.
Country Code: Users please select the desired country code.
Long Distance Call Prefix Digit: The long-distance prefix digit for making a long-distance call.

If you fail to make a call, please contact your ITSP.
NOTE: All settings in this section are specific to your VoIP network. Please ask your VoIP service
provider whether or not they require these settings.
