3.3.4.8.4 Configuring the Internal DNS Table
The 'Internal DNS Table' page, similar to a DNS resolution is used to translate up to 20 host
(domain) names into IP addresses (e.g., when using the 'Tel to IP Routing' table. Up to four
different IP addresses can be assigned to the same host name, typically used for
alternative routing (for Tel-to-IP call routing).
Notes:
To configure the internal DNS table:
1. Open the 'Internal DNS Table' page (Configuration tab > Protocol Configuration
menu > Routing Tables submenu > Internal DNS Table page item).
2. In the 'Domain Name' field, enter the host name to be translated. You can enter a
string of up to 31 characters long.
3. In the 'First IP Address' field, enter the first IP address (in dotted-decimal format
notation) to which the host name is translated.
4. Optionally, in the 'Second IP Address', 'Third IP Address', and 'Second IP Address'
fields, enter the next IP addresses to which the host name is translated.
5. Click the Submit button to save your changes.
6. To save the changes to flash memory, refer to ''Saving Configuration'' on page 167.

The source IP Group (1-9) associated with the incoming IP-to-Tel
call. This is the IP Group from where the INVITE message
originated. This IP Group can later be used as the 'Serving IP
Group' in the Account table (refer to ''Configuring the Account Table''
on page 102) for obtaining authentication user name/password for
this call.
•
The device initially attempts to resolve a domain name using the Internal
DNS table. If the domain name isn't listed in the table, the device
performs a DNS resolution using an external DNS server.
•
You can also configure the DNS table using the ini file table parameter
DNS2IP (refer to ''DNS Parameters'' on page 223).
