Table 5-15: IP to Trunk Group Routing Table
Parameter Description
Any H.323 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 hunt 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
5.5.3.1 on page 95.
Trunk Group ID In each of the Trunk Group ID fields, enter the trunk group ID to which calls that
match these prefixes are assigned.
Profile ID Enter the number of the IP profile that is assigned to the routing rule.
5.5.4.4 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, ‘Gatekeeper IP Address’). 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).
For a description of the ini file parameter (DNS2IP) used to configure the Internal DNS
table, refer to Section 6.5.1 on page 212.
Note: When the DNS table is used to resolve Gatekeeper domain names, only
the first IP address is used.
