If you select LAN or Any_WAN, the VDSL Router automatically
activates the VoIP service when any LAN or WAN connection is up.
If you select Multi_WAN, you also need to select the pre-configured
WAN connections. The VoIP service is activated only when one of the
selected WAN connections is up.
Outbound Proxy
Outbound Proxy
Address
Enter the IP address or domain name of the SIP outbound proxy server
if your VoIP service provider has a SIP outbound server to handle voice
calls. This allows the VDSL Router to work with any type of NAT router
and eliminates the need for STUN or a SIP ALG. Turn off any SIP ALG on
a NAT router in front of the VDSL Router to keep it from re-translating
the IP address (since this is already handled by the outbound proxy
server).
Outbound Proxy
Port Enter the SIP outbound proxy server’s listening port, if your VoIP
service provider gave you one. Otherwise, keep the default value.
RTP Port Range
Start Port
End Port
Enter the listening port number(s) for RTP traffic, if your VoIP service
provider gave you this information. Otherwise, keep the default values.
To enter one port number, enter the port number in the Start Port and
End Port fields.
To enter a range of ports,
• enter the port number at the beginning of the range in the Start
Port field.
• enter the port number at the end of the range in the End Port field.
