ƒEnable the DMZ configuration on the residential router for the LAN port where the V7122 gateway is connected. This enables unknown packets to be routed to the DMZ port.

2When working with a Gatekeeper, under H.323 Parameters, set the Working with Gatekeeper field to Yes, and then enter the IP address of the primary Gatekeeper in the Gatekeeper IP Address field. When no Gatekeeper is used, the internal routing table is used to route the calls.

3Leave Enable Annex D/T.38 FAX Relay parameter at its default unless your technical requirements differ.

4Select the coder (that is, vocoder) that best suits your VoIP system requirements. The default coder is: G.723.1 30 msec. To configure the entire list of coders you want the V7122 gateway to use, see the V7122 Digital Gateway User Guide.

5Map outgoing calls to IP addresses (when Gatekeeper is not used) by completing these steps:

a)Click the arrow button next to the Tel to IP Routing Table label; the Tel to IP Routing screen opens.

Any telephone number whose destination number matches the prefix defined in the Destination Phone Prefix field and whose source number matches the prefix defined in the adjacent Source Phone Prefix field, is sent to the IP address entered in the IP Address field.

b)Click Submit; the Tel to IP Routing table is automatically updated.

c)Click Quick Setup; you are returned to the Quick Setup screen.

For more information about the Tel to IP Routing table, see the 7122 Digital Gateway User Guide.

6Enable E1/T1 B-channels by completing these steps:

a)Click the arrow button next to the Trunk Group Table label; the Trunk Group Table screen opens.

b)Select the number of the trunk you want to enable from the Trunk ID drop-down list.

c)Enter the number of B-channels you want to enable in the Channels field.

d)Enter the starting phone number in the adjacent Phone Number field (these are virtual numbers, used only to define enabled B-channels).

e)Click Submit; the Trunk Group Table is automatically updated.

f)Click Quick Setup; you are returned to the Quick Setup screen.

7Click the Reset button, and then at the prompt click OK; the V7122 gateway applies the changes and restarts. This takes approximately three minutes to complete. When the V7122 gateway has finished restarting, the Ready and LAN LEDs on the front panel are lit green.

8After the gateway is reset, configure the V7122 gateway trunk parameters. For information on configuring the trunk parameters, see Configuring the Trunk Settings.
