Mediant 2000 SIP User's Manual
Parameter
Any SIP incoming call whose destination number matches the prefix defined in the 'Destination Phone Prefix' field and
its source number matches the prefix defined in the adjacent 'Source Phone Prefix' field and its source IP address
matches the address defined in the 'Source IP Address' field, is assigned to the trunk group entered in the field to the
right of these fields.
Note that IP to trunk group routing can be performed according to any combination of source / destination phone
prefixes and source IP address, or using each independently.
Note: For available notations that represent multiple numbers (used in the prefix columns), refer to Section
page 47.

Internal DNS Table
The internal DNS table, similar to a DNS resolution, translates hostnames into IP addresses. This
table is used when hostname translation is required (e.g., 'Tel to IP Routing' table, etc.). Two
different IP addresses can be assigned to the same hostname. If the hostname isn't found in this
table, the gateway communicates with an external DNS server.
Assigning two IP addresses to hostname can be used for alternative routing (using the 'Tel to IP
Routing' table).
To configure the internal DNS table, take these 7 steps:
Open the 'Internal DNS Table' screen (Protocol Management menu > Routing Tables
1.
submenu > Internal DNS Table option); the 'Internal DNS Table' screen is displayed.
In the 'DNS Name' field, enter the hostname to be translated. You can enter a string up to 31
2.
characters long.
In the 'First IP Address' field, enter the first IP address that the hostname is translated to.
3.
In the 'Second IP Address' field, enter the second IP address that the hostname is translated
4.
to.
Repeat steps 2 to 4, for each Internal DNS Table entry.
5.
Click the Submit button to save your changes.
