To provision basic H.323 parameters take these 9 steps:
1. If the Mediant 2000 is behind a router with NAT enabled, take the following procedures:
Determine the "public" IP address assigned to the router (by using, for instance, router
Web management). This "public IP address" is used to configure the Mediant 2000
Static NAT IP address.
Enable the DMZ configuration on the residential router for the LAN port where the
Mediant 2000 gateway is connected.
Enter the public IP address for the Mediant 2000 in the 'NAT IP Address' field (in
addition to the gateway's local IP address).'
2. In the 'Default Gateway IP Address' field, enter the IP address for the default gateway. If you
do not know the IP address for the default gateway, contact your network administrator.
Enter 0.0.0.0 if default gateway isn't used.
3. When working with a Gatekeeper, set 'Working with Gatekeeper' field, under 'H.323
Parameters', 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.
4. Leave parameter 'Enable Annex D/T.38 FAX Relay' at its default unless your technical
requirements differ.
5. Select the coder that best suits your VoIP system requirements. The default coder is: G.7231
30 msec. To program the entire list of coders you want the Mediant 2000 to use, click the
button on the left side of the '1
appear. Select coders according to your system requirements. Note that coders higher on
the list take precedence over coders lower on the list.
