proxy server with the domain name you filled in. Otherwise, the VoIP Gateway will register to a SIP proxy
server with the IP it resolves.
Use Domain to Register: Check the box to use Domain to register with SIP proxy server. The VoIP
Gateway is registered to the SIP proxy server with IP address if un-ticked.
Note: Proxy Server Realm, SIP Domain and Use Domain to Register are the parameters provided
by VoIP Service Provider. If you fail to make a call, please contact your VoIP Service Provider.
Outbound Proxy Support: Check the box to send all SIP packets to the destined outbound proxy server.
An outbound proxy server handles SIP call signaling as a standard SIP proxy server would do. Further, it
receives and transmits phone conversation traffic (media) between two communication parties. This option
tells the VoIP Gateway to send and receive all SIP packets to the destined outbound proxy server rather
than the remote VoIP device. 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.
Outbound Proxy IP/Domain: Enter the outbound proxy's IP address or URL.
Outbound Proxy Port: Enter the outbound proxy's listening port.
Bind Proxy Interval for NAT: Check the box to keep the binding exist by sending packets when the VoIP
Gateway is behind a NAT and SIP proxy server is not able to keep the binding.
Initial Unregister: Check the box to send an unregistered message initially by the VoIP Gateway and then
it will perform a general register process.
Unregister All Contacts: DVG-6004S sends un-register request to SoftSwitch which the contact field filled
with a start sign(*) to un-register all FXO in this DVG-6004S.
Keep SIP Auth: VoIP GATEWAY keeps the last register SIP MD5 authentication information and re-use it
for next register request.
Support Message Waiting Indication (MWI): It is used to enable/disable Message Waiting Indication. It is
available only when Voice Mail Service is available from the VoIP Service Provider.
