Setup’ screen is displayed, shown in Figure

¾ To configure basic H.323 parameters, take these 8 steps:
1. If the Mediant 1000 is connected to a router with NAT 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 configuration on the residential router for the LAN port where the
Mediant 1000 gateway is connected. This enables unknown packets to be routed to the
DMZ port.
2. When working with a Gatekeeper, under ‘H.323 Parameters’, set ‘Working with Gatekeeper’
field to ‘Yes’ and enter the IP address of the primary Gatekeeper in the field ‘Gatekeeper IP
Address’. When no Gatekeeper is used, the internal routing table is used to route the calls.
3. Leave parameter ‘Enable Annex D/T.38 FAX Relay’ at its default unless your technical
requirements differ.
4. Select the coder (i.e., vocoder) that best suits your VoIP system requirements. The default
coder is: G.723.1 30 msec. To program the entire list of coders you want the Mediant 1000
to use, refer to the digital Mediant 1000 User’s Manual.
