4.3 Configuring the Gateway's Basic Parameters
To configure the gateway's basic parameters use the Embedded Web Server’s ‘Quick
Setup’ screen (shown in Figure
4-1 below). Refer to Section 5.3 on page 58 for information
on accessing the ‘Quick Setup’ screen.

¾ To configure basic SIP parameters, take these 10 steps:
1. If the gateway is connected to a router with NAT (Network Address Translation)
enabled, perform the following procedure. If it isn’t, leave the ‘NAT IP Address’ field
undefined.
• Determine the ‘public’ IP address assigned to the router (by using, for instance,
router Web management). Enter this public IP address in the ‘NAT IP Address’
field.
• Enable the DMZ (Demilitarized Zone) configuration on the residential router for
the LAN port where the gateway gateway is connected. This enables unknown
packets to be routed to the DMZ port.
2. Under ‘SIP Parameters’, enter the gateway's domain name in the field ‘Gateway
Name’. If the field is not specified, the gateway's IP address is used instead (default).
3. When working with a Proxy server, set ‘Working with Proxy’ field to ‘Yes’ and enter the
IP address of the primary Proxy server in the field ‘Proxy IP address’. When no Proxy
is used, the internal routing table is used to route the calls.
4. Enter the Proxy name in the field ‘Proxy Name’. If Proxy name is used, it replaces the
Proxy IP address in all SIP messages. This means that messages is still sent to the
physical Proxy IP address but the SIP URI contains the Proxy name instead.
