Table 5-21: IP to Trunk Group Routing Table
Parameter Description
Source IP Address
Represents the source IP address of an IP-to-Tel call (obtained from the
Contact header in the INVITE message).
Note: The source IP address can include the 'x' wildcard to represent
single digits. For example: 10.8.8.xx represents all the addresses
between 10.8.8.10 to 10.8.8.99. In addition, the source IP address can
include the asterisk (*) wildcard, which represents any number between 0
and 255. For example, 10.8.8.* represents all addresses between
10.8.8.0 and 10.8.8.255.
Any SIP incoming call whose destination number matches the prefix defined in the 'Dest. Phone
Prefix' field, and whose source number matches the prefix defined in the adjacent 'Source Phone
Prefix' field, and whose source IP address matches the address defined in the 'Source IP Address'
field is assigned to the Trunk Group in the corresponding 'Trunk Group ID' field.
Notes:
 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.
 For available notations that represent multiple numbers (used in the prefix columns), refer to
'Dialing Plan Notation' on page 116.
Trunk Group ID
Trunk Group ID to which calls that match these prefixes are assigned.
Profile ID
Number of the IP profile that is assigned to the routing rule.
5.5.4.4 Internal DNS Table
The Internal DNS Table option, similar to a DNS resolution, is used to translate host
names into IP addresses. It is used when hostname translation is required (e.g., 'Tel to IP
Routing' table). 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 'Networking Parameters' on page 273.
Note: If the Internal DNS table is configured, the gateway first tries to resolve a
domain name using this table. If the domain name isn't found, the gateway
performs a DNS resolution using an external DNS server.
